pp.); 8. Quantitative analysis (32 pp.); 9. Applications
and techniques (92 pp.). The emphasis of the book is
quite clearly on practical aspects. Nevertheless, all the
important equations derived from theory are included in
the most concise possible form. It would be wrong to regard
this merely as a dutiful exercise in theory, since important
practical conclusions are almost invariably derived from
the relationships. The two chapters on columns and applications merit special mention. Containing 263 and 809
literature references respectively, they not only provide a n
excellent survey but represent well-balanced and selfcontained treatises containing all the essential details.
Happily, there is none of the overlapping all t o o often observed in multi-author volumes. All the authors use the
same symbols which are collected together in a single list.
I t is unfortunate that out-of-date statements, now recognized as incorrect, are made in the discussion of the van
Deemter equation o n p. 23, in connection with mass transport in the mobile and the stationary phase. This is evidently due to the fact that the author of this chapter has relied
o n a (cited) paper whose experimental conditions were inappropriate to the theoretical conclusions based upon them.
In its nine chapters the book presents all the essential points
of gas chromatography. I t is particularly suitable for all
those who are daily confronted by analytical and experimental problems of gas chromatography, and can be recommended as a really excellent work.

Methods in Free-Radical Chemistry. Edited by E. S. Huyser.
Marcel Dekker Inc., New York 1969, 1st Edit., Vol. 1:
208 pp., numerous illustrations, bound $11.75. Vol. 2: xi,
242 pp., numerous illustrations, bound $12.75.
Since the publication of C. Walling’s book “Free Radicals in
Solution” in 1957, such extensive progress has been made in
this branch of chemistry that it would no longer be possible
for a single author to present a comprehensive treatment. As
in other fields, therefore, monographs in free-radical chemistry are being replaced by progress reports covering a limited
area. The present new series can consequently claim a place
of special importance alongside “Advances in Free-Radical
Chemistry” [I]. A wide selection of the results of work carried
out in free-radical chemistry over the past twelve years is
discussed in a total of five sections by young authors working
in this field.
The first two chapters (Free Radical Study by Electron Paramagnetic Resonance by L. Kevan, 35 pp.; Free Radical and
Photochemical Reactions by D . C. Neckers, 44 pp.) are dominated by the discussion of the methods and their theoretical
principles on the basis of selected results. Their value lies in
the concise and lucid survey and in the references to the original literature. The sections “Free-Radical Chlorinations”
( M . L. Poutsma, 114 pp.), “Free Radical Brominations” ( W .
A. Thaler, 106 pp.), and “Thiyl Radicals” ( R . M. Kellog,
120pp.), o n the other hand, deal systematically from the
preparative and mechanistic standpoints with free-radical
substitutions and additions of free radicals. The important
relations between structure and reactivity are clearly recognizable from the numerous tables and diagrams. These chapters undoubtedly constitute the more valuable part of the
present work, since the literature, which would now be very
difficult to scan, is reviewed critically and comprehensively up
to the latest position.
In presentation and quality, the two volumes may be regarded
as supplements to Walling’s classic work. They should therefore find a place in every library and are especially recommended to all those who are interested in free-radical chemistry.

Laser -man
Spectroscopy. By T. R . Gilson and P . J .
Hendra. Wiley-Interscience, Division of J. Wiley and
Sons, New York 1970. 1st Edit., ix, 266 pp., numerous
illustrations, bound, 90s.
Although laser light sources have considerably simplified
the techniques of Raman spectroscopy, the term “laser
Raman spectroscopy” is no more appropriate than “Nernstlamp infrared spectroscopy”. This is one of the faults of
the present book, which is meant to be “an introduction to
Raman spectroscopy with particular emphasis on the developments resulting from the use of laser sources”. It is
divided into the following sections: 1. Introduction (20 pp.),
2. Experimental (40 pp.), 3. Raman Intensity and Depolarization Ratios (23 pp.), 4. Single-crystal Raman Spectroscopy (58 pp.), 5. Raman Spectra of Gases (11 pp.).
6. Powders, Liquids and Solutions (13 pp.), 7. Polymers
(17 pp.), 8. Miscellaneous Raman Experiments (15 pp.),
9. Sources of Information (3 pp.). There are two appendices, one devoted to lasers (I, 6 pp.) and the other to
“Results from Group Theory” (11, 47 pp.).
The first four chapters are instructive and useful. The
beginner, however, would profit more from Chapter 4 and
Appendix I1 if examples had been treated in detail and
knowledge of the original work had not been presupposed,
as is the case o n pp. 109-123. The later chapters show evidence of unquelled enthusiasm over laser light sources
(“Laser has revolutionized the study” (of polymers) p. 166).
One learns a great deal about the successful recording of
individual spectra but not enough about how useful this is.
An unexperienced reader would doubtless get the impression that Raman spectroscopy was a very new method and
that a large store of experience in the field of “mercury-lamp
Raman spectroscopy”, as collated for example in the books
of Kohlrausch, Herzberg, and Siebert, did not exist. The
book is also disappointing for the organic chemist. Only one
page (155) is given to structural determination and there are
only nine lines (p. 165), without references, o n his main
concern, the detection of compounds whose vibrations in
the infrared are t o o weak. The reader is told nothing of the
important problem of appropriate sample preparation and
the dependence of intensity o n the grain size in powders.
Chapter 9 makes n o mention either of the very useful DMS
Reference Service “IR Raman Microwaves” which has
been operating since 1963, or of the spectra collections of
the API and in Landolt-Bornstein. Printing errors are rare.
The book would be more useful for beginners and for
specialists if the last chapters in particular were thoroughly
revised.

The Halides of the Lanthanides and Actinides. By D . Brown.
John Wiley and Sons Ltd., London-New York-SydneyTokyo-Mexico City. 1968. 1st Edit., x, 280 pp., numerous
illustrations, bound, ca. D M 43.--.
Until recently only two review papers have been available o n
the halides of the f transition elements, namely one on the
lanthanoid halides [IJ[*l and one o n the actinoid halides [21[*1.
D . Brown, who is himself a n authority in the field of the
actinoid and lanthanoid halides, has now attempted to
present a comparative description of the halides of all the f
transition elements. This attempt may be regarded as
highly successful. One’s only regret is that the halides of the
transcurium elements were discovered too recently to be
included in this book.
