aw earance of this book has been eagerly anticipated ever since a most successful NATO-AS1 on this topic was organized in Be&ate, Italy by the editors in 1977. The wait has been worthwhile. This volume is the first comprehensive account of the varying approaches to the intensity problem. It is destined to become a “classic”. As such hopefully it will be instrumental in persuading non-experts that Bryce Crawford, Jr’s, contention that we are on the brink of a renaissance in intensity studies is well-founded. Vibrational spectra provide three experimental data: frequencies, band shapes and intensities_ The importance of frequencies is well-established and band shape analysis is being vigorously pursued in many centres. The study of band intensities has been the poor relation due mainly to experimental difficulties, now overcome, and to the fact that no single theory emerged as chief contender for the analysis of the data in terms of molecular parameters_ The paucity of intensity studies in earlier years was due to the difficulties encountered in interpreting the data. These were centred on sign ambiguities of the polar parameters derived, the accuracy with which normal coordinates could be calculated and those associated with the choice of particular models such as the bond-moment hypothesis, electro-optical theory or the polar tensor approach. To a great extent these difficulties have been overcome and the methods used are described in this book by world experts who have led the successful assault on this particular intellectual battle. The contributions in this volume are based on the Be&rate conference and provide the only complete account of vibrational intensities available to all spectroscopists/theoreticians interested in one of the most exciting growth points in current research. A. J. B. Molecular Vibrational-Rotational Spectra, by D. Papousek and M. R. Aliev, Elsevier, Amsterdam, 1982, pp. 323, price $90.75. The authors have provided a first-rate modem treatment of the theory of vibrational-rotational spectra of semi-rigid molecules. Included are excellent accounts of molecular symmetry as applied to rigid as well as non-rigid molecules, a new theory of higher-order effects, and a description of large amplitude vibrational motions. This book is written from the fundamental point of view. The results
