classified as “solid solutions” and “multiple compounds”. The variable composition of the spinels can only be accounted for by designating them as “more complicated multiple compounds”. In contrast, the discussion of reactivity at phase transition points is quite stimulating. The chapter on ‘Y% rface Properties” reports interesting results on the variation of dehydration rate with crystal habit. The final three chapters discuss a miscellany of topics and evidently aim to cover most aspects of the subject. The book would have benefitted from both editing and proof-reading by English persons, but the overall result is not too bad. The pages are reproduced from letterspaced typewriting with no justification of the lines. This gives a rather faint appearance to the work and makes it less attractive to read; one could reasonably expect professional typesetting in a work of this price. Mr. L. Vielvoye’s diagrams are excellent, as also is the binding. L. L. B.

Vibrational Spectra and Structure, edited by James R. Durig, Vol. 8, Infrared Interferometric Spectrometers, by A. D. Martin, Elsevier, Amsterdam, 1980, pp. 292, price U.S. $73.25.

In his general preface to this excellent series, Dr. Durig states that “one people to (write critical reviews) in conveniently small areas”. He is to be congratulated therefore in persuading Dr. A. E. Martin, who (in 1950) produced the first commercial infrared spectxometer in the UK, to write this comprehensive text on the theoretical background of Fourier Transform Infrared (FTIR) spectroscopy. Read in conjunction with Durig’s “Analytical Applications of FT-IR to Molecular and Biological Systems”, (D. Reidel, The Netherlands, 1980) which covers many of the applications, the reader is rapidly convinced that FTIR has already, in its brief lile, fulfilled the expectations of its progenitors. In addition to covering the theoretical background in a thorough but attractively simple manner, Dr. Martin provides brief accounts of the instrumentation available commercially and also the techniques used. Amongst other useful chapters, those on computation, measurement of refractive index and other interferometers are especially noteworthy. The text is written in a clear and concise fashion, considerably helped by the provision of 13 appendices containing much of the necessary mathematical material. The high reputation of this series is considerably augmented by the of the greatest needs of science today is for competent
