Semiclassical methods in molecular scattering and spectroscopy

many other authors do the same. But renaming the sulfo (-SO$I) group (or is he referring to its deprotonated sulfonato form?) as ‘sulphityl’ is confusing. Luckily context explains that his ‘diacyl methionyl, mono-Bocderivative’ is substituted three times (including twoN-acylmethionyl groups). not four. Many of the methods given were devised by Offord and his colleagues. One particularly elegant one is the synthesis of a diazomethane that has been substituted by an aromatic sulfonic acid, so that this reagent (sodium 5diazomethyl-Z-methoxybenzensulfonate) esterifies carboxyl groups but the product formed remains negatively charged. I think there are few protein chemists who have not much to gain from this book. H. B. F. D. Semiclassical Methods in Molecular Scattering and Spectroscopy, edited by M. S. Child, D. Reidel, Dordrecht, 1980, pp. vii + 332, price Dfl. 75.00. ISBN 90-277-I 082-l. Admirably promptly the proceedings of the NATO advanced study institute held in September 1979 have appeared in book form. It provides a comprehensive introduction to the development of semiclassical methods for molecular scattering and spectroscopy in the twenty years since the classic paper of Ford and Wheeler. During this period there have been advances in mathematical technique which are covered in two chapters by Frijman and LeRoy. The editor himself covers spectroscopic applications and scattering is the subject of chapters by Lam and George, by Connor and by Dickinson. Handy contributes the final chapter on the determination of bound states of nonseparable situations. The advances in chemical physics which have led to very precise experiments, coupled with the developments in computing, make this area one of the most stimulating in current theoretical chemistry_ Here is the perfect introduction for the serious graduate student or researcher entering the field, complete with problems at the end of each chapter. The book should open a perhaps unfamiliar area of research to a wider audience. W. G. R. Organometallic Chemistry, Vol. 8, senior reporters E. W. Abel and F. G. A. Stone, Specialist Periodical Report, The Chemical Society, London, 1980, pp. xx + 547, price $44.00. ISBN O-85186-690-5. The latest volume in this well-established series provides a comprehensive review of the literature published during the calendar year 1978, and is concerned with the synthesis, structure, and chemical and physical properties of compounds of the main-group and transition metal elements containing
