This book is not for the novice in NMR. Nor is it for the theoretician; there are only a few summations to be found in its pages and positively no integrals. In fact, the scope of the work would be more exactly defined in the title if “nuclear” were replaced by “proton,” since nuclei other than hydrogen receive scant attention and that only where they couple with protons. Its approach is that of the practising organic chemist who needs to know what correlations have been established between molecular structure and the parameters obtainable from proton resonance spectra. Exhaustive details of theoretical calculations or spectral analysis are not given, but copious reference is made to an encyclopedic bibliography of 2659 references which covers the significant literature until 1966. It is unfortunate that the unusual delay in publication has made this review less current than it might have been, but the gap has been filled by several current review series in NMR. This bibliography is one of the great strengths of the book, the others being the vast experience of the authors in organic structure determination and their approach to the subject, which, although nonmathematical and pragmatic, is fully cognizant of underlying theory and its useful results. Particular attention is paid to popular pitfalls such as “virtual” coupling, methylene nonequivalence, and the uses and abuses of the Karplus relation, and there are excellent discussions of basic proton chemical shift theory and long-range coupling. Also well-treated are relaxation, anisotropic shielding, and referencing (the delta scale is used throughout). Perhaps in view of the practical attack of this work more emphasis might have been laid on the peculiar and misleading antics of some simple spin systems, the reader merely being directed to the literature for their analysis. There are many valuable tables of model compounds for chemical shifts and couplings, again fully annotated; the book will prove an invaluable entrance to the literature for the chemist who has no opportunity to read all the journals into which proton magnetic resonance has now spread. Jackman and Sternhell write in good Anglo-American and have produced what may be the best advanced organic NMR text yet published; a worthy successor to the pioneering first edition. ROY W.

Magnetic Domains. By R. S. TEBBLE. Methuen, London, 1969 (U.S. Distributor and Noble, New York). xxi + 100 pp. + plates. $4.00.

This brief book of 100 pages is an introduction to domain structure for students and for engineers and scientists previously unacquainted with magnetic domains. In it, the standard experimental methods of observing domains, the Bitter or powder pattern technique, transmission electron microscopy, and magnetooptical methods are described and illustrated with a nice collection of pictures. Of interest to instructors of magnetism is the book’s explanation of the magnetization curve in terms of the structure and properties of domains. Since domains exist because energy is minimized by their presence, the relevant energy considerations in magnetic materials are discussed in some detail. In response to their commercial significance, the author devotes a chapter each to the problem of a single domain particle and to the domain structure of thin films. 319
