Ekfrm Spin Relaxatim iwxLiquids, edited by L. T. MUUS ANDP. W. ATKINS, Plenum Press, New York, 1972, pp. xiv + 537, price 829.50. This volume is based on lectures delivered at tha NATO Advanced Study Institute held in Sp%tind in August 1971. It is a camprehensive collection of mater&f on advanced mathematicssl zechniques wIrich can be appkd to dectr~n spin relaxation in liquids and deals with “huw thuse who are concerned with spin relaxation problems think z&out the subject and circumvent, or expose, its diBk& ties”. fnciuded in its discussions are: basic quantum mechanical and statistical manipulations; general theory of linear response; a review of the entire field of application of the theories is given separately and this is invaluable for continuing reference. There are chapters on spin rotation theory, “S ions and the study of slcrw avid anisotropic motion, The whole is a thorough and sound consideration of the relations of theory and the most recent developments are brought under critica examination_ 3. w, ~~~~Spec~r~merry,s~ni;ol; reporter D.

The articles are well written and at L7.00 this book represents excellent value for money. It is an essential reference source for anyone working in the appropriate fields. This reviewer would like to see either the series extended to cover the other chemical aspects of mass spectrometry, e.g. physico-chemical, analytical, or the title modified to show that it is devoted to the mass spectra of organic and organometallic compounds.

1971,

This book sets out to present the energetics of chemical systems in such a way as to be understandable to the reader under the conditions of individual study. It is a very readable text covering as wide a range of topics under the title heading as one might reasonably expect in a book of this size. In style the text tends perhaps to be a little “lecture note like” in format, but in a small book like this the lengthy detail and description often found in heavier tomes may be left out with some advantage to the student. A dominant feature of the text is the emphasis on examples (worked and ’ set). Thought provoking and pertinent questions within the chapters help to illustrate and one hopes remove theconfusion in some students’minds between thermodynamics and kinetics when discussing the feasibility and speeds of reactions. In the reviewer’s opinion this is a very good addition to the literature for its set purpose, and will help many students by developing their interest in, and understanding of this branch of the subject. W. E. S. Fit&Z-ion Microscopy, by K. M. BOWKETT AND D. A. SMITH, North-Holland Publishing Company, Amsterdam, 1970, pp. x+257, price k6.30. Despite important contributions to the study of chemisorption, surface diffusion, and the defect solid state, the fieId electron emission/field-ion microscope has not received such rapid and widespread acceptance as many more elaborate and costiy techniques of analysis. Nevertheless this monograph, volume 2 of a series on defects in crystalline solids, has already begun to prove its value as a laboratory handbook of field-ion microscopy. The authors emphasize the application of FIM to metallurgical studies of bulk structure, rather than its uses
