The theory of magnetic resonance
446
NMR and Chemistry, by J. W. Akitt, Chapman and HalI, London, 1973, pp- ix + 182, price s1.95. This is a non-specialist text written for undergraduates, giving a general account of the whole field of NMR. The first of the two sections covers the theory of NMR, using a straightforward non-mathematical approach. Nuclear properties, nuclear screening and internuclear spin-spin coupling are dealt with in the first three chapters. Chapter 4 introduces relaxation, the Bloch equations and double resonance experiments. The following chapters consider standardization and solvent effects of the sample, and instrumentation. The second section deals with the use of NMR in chemistry, for instance, structure determination, measurements of reaction rates and mechanisms. There are over forty specific examples taken from all branches of chemistry, some of which are worked out, while others are presented as problems. T. W. The Theory of Magnetic Resonance, by C. P. Poole, Jr. and H. A. Farach, Wiley-Interscience, New York, London, Sydney and Toronto, 1972, pp_ xiv + 452, price 3X0.70, There have been several attempts to present magnetic resonance as a unified topic rather than as the separate but similar disciplines of, for example, electron spin resonance, nuclear magnetic resonance, quadrupole, atomic and Mossbrauer spectroscopies, but it is doubtful if any have achieved the success of this book. The success stems largely from a sense of its limitations rather than from an attempt to be comprehensive. This is not the standard reference text, but anyone who has worked through the book will be adequately equipped to approach the more formidable standard texts such as those by Abragam and by Abragam and Bleaney. The book is to some extent unfashionable in that there is little attempt to treat time-dependent systems (these are handled in a companion volume) but this restriction adds to the unity of the book since all phenomena described can be treated by the direct product matrix expansion technique. The approach throughout, is to treat the general case first then to approximate to the more useful special cases. There are good discussions of isotropic and anisotropic effects, of multi-spin and high spin systems, of quadrupole effects, zero field splittings, Mossbauer resonance, atomic spectra and crystal field theory with a final chapter on line shapesuseful Appendices include a set of problems and a good bibliography. The book has grown out of a series of lectures, and the unity of approach throughout the book makes it a very valuable addition to any advanced undergraduate or post-graduate course, whilst the specialist will certainly appreciate the unity of approach.
