Description
Book SynopsisThis book describes in mathematical terms the extraction of useful information from ESR spectra as applied to paramagnetic organic, inorganic and organometalic molecules. It lays a firm groundwork for understanding more sophisticated experiments, which the availability of newer commercial instruments has made possible. It takes the reader step by step through obtaining and interpretating ESR spectra of paramagnetic molecules. The mathematical basis of each observed phenomena are detailed and examples given. In particular there is a detailed discussion of 2nd order pertubation theory treatment of the Spin Hamiltonian for non-coincident G and A axes.
Trade Review"It is a very welcome addition to the literature in the field of EPR spectroscopy....its approach is fresh and didactically sound. The book is accessible to a broader readership than existing textbooks.The selection of topics is well balanced. A student who reads through this book will acquire a solid repertoire of methods for interpreting even complicated EPR spectra....For experienced researchers the book is well suited as a dictionary of spectrum analysis....clear and simple figures are well suited for illustrating lectures. There are not many books that I could recommend with such a good conscience as this one. Personally, I now regard it as an essential item on my bookshelf." * Angewandte Chemie, International Edition, 2008, 47 2913-2914 (Gunnar Jeschke) *
"I would also like to compliment you on the very fine production of the monograph." * University of Manchester, 10th September 2007 (Prof David Collison) *
