    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 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.

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...

  • Vibrational Spectroscopy of Solids Cambridge Monographs in Physical Chemistry

    Cambridge University Press Vibrational Spectroscopy of Solids Cambridge Monographs in Physical Chemistry

    15 in stock

    Book SynopsisThis 1972 monograph is devoted to the analysis and interpretation of the infrared and Raman spectra of solid compounds, frequently used for their identification and characterization. It was thought unsatisfactory to analyse such spectra by the theory applicable to gas-phase samples, though this was frequently done. Furthermore, the results obtained by far infrared and laser Raman spectrometers, which detect the movement of atoms and/or molecules as a whole, had no gas-phase analogy. A separate approach to solid state vibrational spectra was therefore proposed within this volume. Dr Sherwood describes the solid state physics of vibrational spectroscopy and extends it to the more complex structures of low symmetry. He assumes an understanding of the infrared and Raman spectra of gases.Table of ContentsPreface; 1. Introduction; 2. Phonons and lattice vibrations; 3. The application of group theory to a crystal lattice; 4. The interaction of radiation with a crystal; 5. Second order vibrational spectroscopic features; Appendix: character tables; References; Glossary of terms; Index.

    Book SynopsisPhoton-in-photon-out core level spectroscopy is an emerging approach to characterize the electronic structure of catalysts and enzymes, and it is either installed or planned for intense synchrotron beam lines and X-ray free electron lasers. This type of spectroscopy requires high-energy resolution spectroscopy not only for the incoming X-ray beam but also, in most applications, for the detection of the outgoing photons. Thus, the use of high-resolution X-ray crystal spectrometers whose resolving power ?E/E is typically about 104, is mandatory.High-Resolution XAS/XES: Analyzing Electronic Structures of Catalysts covers the latest developments in X-ray light sources, detectors, crystal spectrometers, and photon-in-photon-out core level spectroscopy techniques. It also addresses photon-in-photon-out core level spectroscopy applications for the study of catalytic systems, highlighting hard X-ray measurements primarily due to probe high penetration, enabling in situ Table of ContentsX-Ray Sources and Detectors.

    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.
