These t,opics are covered in 39 pages and t,his is indicative of the brevity of the t,reat,ment of each topic throughout the hook. If a hook is t o "inspire in beginning students an interest" in any topic, i t would seem that the treatment of each subject should he sufficiently detailed so that the student obtains a reasonable understanding as he proceeds. In the opinion of the reviewer, the brevity of treat,ment of topics in this hook is such that very few beginning st,udents would he inspired by it. Forther, i t would seem that even more advanced stndent,~are likely to prefer x more thorough discmsion of most of the topics included in the book.

This ueful book reviews the applicat,ions of several forms of spectroscopy to the elucidation of the structure of metal chelate compounds, and the six articles, each by specialists in the field, stay well within these hounds. Topics covered are: visible and ultraviolet spectroscopy, optical rotatory dispersion and circular dichroism, infrared apectroscopy, electron spin resonance spectroscopy, nuclear magnetic resonance spectroscopy, and, most appropriately today, the book opens with a chapter on X-ray andneutron diffraction analysis (spectroscopy?). Each article begin8 with an introduction to the technique, and then a number of applications to metal chelate compounds are reviewed. The theoretical introduction is usually brief, and cannot be relied upon as a first introduction to the subject a t hand. The principle aim of the book is to review applications, and this is done admirably well. The articles occasionally lapse into the style of the R. L.

The technology of the element and its eompo~~nds, including chlorine dioxide, requires ahant one-fifth of the voltrme. Preparstion and propert.ies of elemental chlorine make up the bulk of the material. Topics include: enrichment and separation of the isotopes, the atom and atomic ions, molecules and molecdar ions, physical properties, eleelrochemical behavior, chemical reaetinns, nonaqneoun solntions, liquid chlorine as a solvent,, and tonicity.

As such, i t is likely t o become outdated in a short time (magnetic circular dichroism is not, discussed, nor is mas3 spectrometry.) All of the articles are well-written and will be osefid, except, fol. that on esr. Only 16 pages long, i t is too short to be of much use to anyone.
