Book SynopsisInductively Coupled Plasma-Atomic Emission Spectroscopy (ICP-AES) has been widely adopted as a routine analytical technique for elemental analysis in both industry and academia. However, spectral interference can be a major problem, particularly with such line-rich elements as the rare earth elements. An Atlas of High Resolution Spectra of Rare Earth Elements, which comes complete with a CD of spectra in full colour, is a reference source suitable for all analytical spectroscopists. Using some previously unpublished high resolution spectra, this atlas enables users of ICP-AES to select the best lines of any single rare earth element matrix. Clear instructions for the use of the accompanying CD are provided, which allows all adjacent interferent spectral profiles to be displayed and superimposed. Up-to-date and informative, this unique book will be welcomed as a practical and indispensable reference guide by all those who use ICP-AES for the analysis of rare earth elements.Trade Review"... a valuable reference guide ..." * Journal of the American Chemical Society, Vol 122, No 18, p 4534 *"... a very useful book to have in the laboratory ..." * Talanta, 52, 2000, 955 *"... a helpful aid to any user of ICP with a special interest in the rare earth elements ..." * Journal of Analytical Atomic Spectrometry, 2000, 15 *"... a welcome addition to the current literature ... should occupy a space in any reference library." * Trends in Analytical Chemistry, Vol 20, No 1, 2001 *"... valuable and indispensable ..." * Fresenius Journal of Analytical Chemistry, 3/2000, M97-M98 *"...

Book SynopsisCD and MCD spectroscopy can provide key information about the conformations and electronic states of chromophore containing molecules. However, the theory has remained too challenging and inaccessible for many organic chemists and biochemists and only a few researchers have carried out detailed quantitative analyses of their spectral data. This is not surprising as people who excel at spectroscopic theory usually lack the skills set required to design and synthesise the molecules that would be most appropriate for describing and explaining the theory of CD and MCD spectroscopy. Most of the books that have been written on the subject have, therefore, been based on very dense sets of mathematical equations. This timely book rectifies that situation by summarizing the relationship between the different types of spectra and by describing in detail the qualitative and quantitative methods which can readily be used to analyse CD and MCD spectral data. During the last decade the authors have successfully synthesized several molecules to illustrate key points related to the theory of CD and MCD spectroscopy, resulting in this definitive book providing key practical knowledge in a readily accessible style. It is aimed primarily at organic chemists and biochemists and provides the required reading for researchers active in the field. In the introduction, the book describes the types of information that can be derived from CD and MCD spectroscopy. After a detailed explanation of the theory of electronic absorption spectroscopy, it then provides practical in depth examples of the various analytical methods that can be carried out with CD and MCD spectral data. This makes the theory of these techniques much more accessible for researchers who do not specialise in physical chemistry.Trade Review"Their explanations of the CD techniques are complete enough to satisfy an expert spectroscopist while at the same time written in a way that can be understood by a non-expert organic chemist that is well versed in introductory physical chemistry." -- Babak Borhan * Angew.

Book SynopsisThis is the physical chemistry textbook for students with an affinity for computers! It offers basic and advanced knowledge for students in the second year of chemistry masters studies and beyond. In seven chapters, the book presents thermodynamics, chemical kinetics, quantum mechanics and molecular structure (including an introduction to quantum chemical calculations), molecular symmetry and crystals. The application of physical-chemical knowledge and problem solving is demonstrated in a chapter on water, treating both the water molecule as well as water in condensed phases.Instead of a traditional textbook top-down approach, this book presents the subjects on the basis of examples, exploring and running computer programs (Mathematica®), discussing the results of molecular orbital calculations (performed using Gaussian) on small molecules and turning to suitable reference works to obtain thermodynamic data. Selected Mathematica® codes are explained at the end of each chapter and cross-referenced with the text, enabling students to plot functions, solve equations, fit data, normalize probability functions, manipulate matrices and test physical models. In addition, the book presents clear and step-by-step explanations and provides detailed and complete answers to all exercises. In this way, it creates an active learning environment that can prepare students for pursuing their own research projects further down the road.Students who are not yet familiar with Mathematica® or Gaussian will find a valuable introduction to computer-based problem solving in the molecular sciences. Other computer applications can alternatively be used. For every chapter learning goals are clearly listed in the beginning, so that readers can easily spot the highlights, and a glossary in the end of the chapter offers a quick look-up of important terms.Table of ContentsThermodynamics.- Chemical Kinetics.- Schrödinger Equation.- Molecular Symmetry.- Molecular Structure.- Crystals.- Water.- Appendix.- Solutions to the Exercises.

Book SynopsisThis book describes the manipulation of molecular properties, such as orientation, structure, and dynamics, of small molecules and molecular clusters isolated in cold inert matrices by using unprecedentedly strong external electrostatic fields. Manipulation of molecules with controllable external forces is a dream of chemists. Molecules are inherently quantum-mechanical systems, control of which potentially can lead to quantum technology, such as quantum sensing and computing. This book demonstrates a combination of the ice film nanocapacitor method and the matrix isolation technique enabled the application of intense external dc electric fields across the isolated molecules and molecular clusters. Changes in molecular states induced by fields were monitored by means of vibrational spectroscopy. Also, the book presents manipulations of the inversion tunneling dynamics of ammonia molecule and the dislocation of acidic proton in hydrogen chloride–water complex. The book shows that the vibrational spectroscopy with the aid of unprecedentedly strong dc electric field can provide rich information on the electrostatic behaviors of molecules and molecular clusters, which underlie the understanding of intermolecular processes and molecular manipulation.Table of ContentsChapter 1.

Book SynopsisThis book is a well-established guide to the interpretation of the mass, ultraviolet, infrared and nuclear magnetic resonance spectra of organic compounds. It is designed for students of organic chemistry taking a course in the application of these techniques to structure determination. The text also remains useful as a source of data for organic chemists to keep on their desks throughout their career. In the seventh edition, substantial portions of the text have been revised reflecting knowledge gained during the author's teaching experience over the last seven years. The chapter on NMR has been divided into two separate chapters covering the 1D and 2D experiments. The discussion is also expanded to include accounts of the physics at a relatively simple level, following the development of the magnetization vectors as each pulse sequence is introduced. The emphasis on the uses of NMR spectroscopy in structure determination is retained. Worked examples and problem sets are included on a chapter level to allow students to practise their skills by determining the chemical structures of unknown compounds.Table of ContentsChapter 1: Mass spectra 1.1 Introduction 1.2 Ion production 1.2.1 Electron impact (EI) 1.2.2 Chemical Ionisation (CI) 1.2.3 Electrospray ionisation (ESI) 1.2.4 Fast ion bombardment (FIB or LSIMS) 1.2.5 Laser desorption (LD) and matrix-assisted laser desorption (MALDI) 1.3 Ion analysis 1.3.1 Magnetic analysers 1.3.2 Time-of–flight (TOF) analysers 1.3.3 Quadrupole analysers 1.3.4 Ion cyclotron resonance (ICR) analysers 1.3.5 Ion-trap analysers 1.4 Structural information from EI mass spectra 1.4.1 The features of an EI spectrum 1.4.2 The molecular ion 1.4.3 Isotopic abundances 1.4.4 Identifying the molecular ion 1.4.5 Fragmentation in EI spectra 1.5 Fragmentation in CI and FIB spectra 1.5.1 Fragmentation in CI spectra 1.5.2 Fragmentation in FIB (LSMIS) spectra 1.6 Some examples of mass spectrometry in action 1.6.1 San Joaquin oil 1.6.2 Oleic acid 1.6.3 The oviposition pheromone 1.6.4 Identifying antibodies 1.6.5 The ESI spectra of melittin and the human parathyroid hormone 1.6.6 ESI-FT-ICR and ESI-FT-Orbitrap spectra 1.7 Separation coupled to mass spectrometry 1.7.1 GC/MS and LC/MS 1.7.2 MS/MS 1.8 Interpreting the spectrum of an unknown 1.9 Internet 1.10 Bibliography 1.11 Problems 1.12 Tables of data Chapter 2: Ultraviolet and visible spectra 2.1 Introduction 2.2 Chromophores 2.3 The absorption laws 2.4 Measurement of the spectrum 2.5 Vibrational fine structure 2.6 Selection rules and intensity 2.7 Solvent effects 2.8 Searching for a chromophore 2.9 Definitions 2.10 Conjugated dienes 2.11 Polyenes and poly-ynes 2.12 Ketones and aldehydes;

Book SynopsisMass spectrometry (MS) is an analytical technique for the determination of the elemental composition of a sample or molecule. It is also used for elucidating the chemical structures of molecules, such as peptides and other chemical compounds. MS instruments consist of three modules: an ion source, which splits the sample molecules into ions; a mass analyser, which sorts the ions by their masses by applying electromagnetic fields; and a detector, which measures the value of an indicator quantity and thus provides data for calculating the abundances of each ion present. The technique has both qualitative and quantitative uses. These include identifying unknown compounds, determining the isotopic composition of elements in a molecule, and determining the structure of a compound by observing its fragmentation. Other uses include quantifying the amount of a compound in a sample or studying the fundamentals of gas phase ion chemistry. MS is now in very common use in analytical laboratories that study physical, chemical, or biological properties of a great variety of compounds. This book gathers the latest research from around the globe in the field.

Book SynopsisThe presented work summarises and systematises an extensive experimental material of the results of studying polymers using spectroscopy in the low-frequency infrared region. Today, spectroscopic studies in the far infrared region are becoming an important tool for characterising the physical properties of polymers, determined by molecular dynamics and the level of molecular interactions. Low-frequency spectroscopy of intermolecular interactions is the original and most informative source and criterion for establishing the presence of a hydrogen bond in biological substances, multiplets and clusters in ionomers, a criterion for crystallinity, etc. Far IR spectroscopy has proven to be productive in deciphering the molecular nature of solid-state (Î'', Î, and Î) relaxation transitions in polymers. This was the result of (1) evaluating the potential barriers and sizes of molecular motion units from the spectra, (2) finding empirical correlations between the spectral parameters and molecular characteristics of polymers, and (3) comparing the results with activation barriers for relaxation transitions.

Book SynopsisNuclear magnetic resonance (NMR) spectroscopy, a technique widely used for structure determination by chemists and biochemists, is based on the detection of tiny radio signals emitted by the nucleus of an atom when immersed in a strong magnetic field. Every chemical substance gives rise to a recognizable NMR signature closely related to its molecular structure. This comprehensive account adopts an accessible, pictorial approach to teach the fundamental principles of high resolution NMR. Mathematical formalism is used sparingly, and everyday analogies are used to provide insight into the physical behaviour of nuclear spins. The first three chapters set out the basic tools for understanding the rest of the book. Each of the remaining chapters provides a self- contained reference to a specific theme, for example spin echoes, and traces the way it influences our understanding of high resolution NMR methodology. Spin Choreography provides a clear and an authoritative introduction to the funTable of Contents1. Energy levels ; 2. Vector model ; 3. Product operator formalism ; 4. Spin echoes ; 5.

Book SynopsisThis is the first book devoted to the use of X-ray beam techniques to study magnetic properties of materials. It covers both experimental and theoretical issues. The three main topics are dichroism, elastic scattering (both non-resonant and resonant diffraction) and spectroscopy.Trade ReviewThis book provides a thorough introduction to both experimental and theretical issues that arise in investigations of materials using the methods of X-ray scattering and absorption * Zeitschrift fur Kristallographie *this monograph, addressing researchers in the field in an elegant, civilised but unpretentious and occasionally idiosyncratic style and vocabulary, sets a high standard for a proposed series on synchrotron radiation * Contemporary Physics Vol. 38 No.5 1997 *Firstly, it is suitable for anyone who would like to become acquainted with a new field of spectroscopy that has made sensational progress over the past decade and, secondly, it is a valuable reference book for those who are already familiar with the techniques... The first part incorporates a great deal of recent work along with many useful tips for the experimentalist and will be readily appreciated by the non-specialist reader... The strength and merit of this book is that both experimental and theoretical issues have been addressed and have been skilfully interwoven. In addition, although magnetic scattering is in the early stages of development, the book establishes a foundation on which further research can be built. * Journal of Synchrotron Radiation, vol. 5, part 3, May 1998 *It must surely play a part in raising the awareness of researchers in magnetism in the potential value of synchrotron-based techniques. The book is suitable for graduate students and researchers with an interest in magnetic materials and for professionals who wish to consider the use of synchrotron radiation in their research... It is surely an indispensable item for the university and the institutional library. * Journal of Synchrotron Radiation, vol. 5, part 3, May 1998 *Table of Contents1. Introductory survey ; 2.
