theoretical, physical, inorganic and organic chemistry. Only in that way will the subject break out of its rather narrow and specialised image. In the UPS field, many authors of papers do not help this cause, since few seek any chemical significance of their work; indeed, more often than not, the spectra of a limited group of compounds or a single species are discussed, with no attempt to correlate results with other ones.

Photochemistry, Vol. IO, senior reporter D. Bryce-Smith, Specialist Periodical Report, The Chemical Society, London, 1980, pp. xxiv + 717, price $40.00. This annual review of photochemistry is now well established, and is certainly one of the most successful of the S.P.R.‘s of The Chemical Society. Volume 10 covers the literature between July 1977 and June 1978. It is immediately clear, as over 700 pages and well over 5000 references attest, that photochemistry continues to boom. These statistics also suggest that this volume is unlikely to be read - even by practising photochemists right the way through. It certainly is a book for browsing and, perhaps, the careful and comprehensive study of particular chapters. The first chapter, which deals with developments in instrumentation and techniques runs to over 100 pages and 1500 references. This illustrates the remarkably rapid progress made in this area in the two years since it was last reported. Indeed, this reviewer believes that this section warrants an annual treatment. The volume has been divided into six parts and The Chemical Society should consider seriously their separate publication. This would allow an individual to purchase the part, or parts, of most interest to him. Any library with a serious chemical section would, of course, need to have the complete work. H. M. F,
Organic Electronic Spectral Data, Vol. XV, edited by J. P. Phillips, D. Bates, H. Feuer and R. S. ‘I’hyagarajan, Wiley, Chichester and New York, 1979, pp. xiii + 1194, price 244.35.
This latest volume in the series covers data published in 1973 in over a hundred journals. The data, as in previous volumes, are arranged in increasing order of complexity of the molecular formulae, and include the Chemical Abstracts name, solvent, wavelengths and logarithms of intensities for all absorption maxima, shoulders, and inflections, followed by the reference code. A fuller reference list concludes the volume. The fifteen volumes provide access to ultraviolet and visible absorption spectra published from 1946 to 1973. This is the period when photoelectric spectrometers became commercially available, thus allowing the ready
