which swell up the book with redundant and erroneous information. This section has apparently not been revised since
the appearance of the first edition in 1944. - The subject
index I s unsatisfactory: it should be more extensive and
built up on a better system of classification.
Despite these shortcomings, the book may be recommended
as a cheap but authoritative introduction to spectroscopy.

Infrared Spectroscopy and Molecular Structure. An Outline of
the Principles. Edited by M. Davies. Elsevier Publishing
Co., Amsterdam-London-New York 1963. 1st Edit., XIII+
468pp., 171figs.,70tables,linenca.DM42.-(about$10.50).
This book is intended for all who use infrared spectroscopy
n3t merely as an empirical fingerprint method but as a theoretically founded process for the investigation ofthe structures
and properties of molecules. Here the theoretical and methodical principles as well as the scope and limitations of the
various applications of infrared spectroscopy are presented
by 13 authorities in clear and understandable terms. The
most important concepts and facts, from both the chemical
and physical points of view, are unraveled so lucidly even
when the material dealt with is complicated that also those
who are less experinced find a good introduction to this discipline. The fact that the authors have concentrated on important examples contributes significantly t o this effect.
The introductory section written by the editor is followed by
chapters on instrumentation and experimental techniques
( A . E. Martin), on long-wave infrared spectroscopy in the
region from 1 to 200cm-1 which has only recently become
utilizable (G. R. Wilkinson), on the infrared spectra of simple
molecules ( W . J . Jones), on the calculation of force constants (J. M. Mills),and on Raman spectra (J. C. Evcins).
The chapter by D . Hndzi on the origin of characteristic group
frequencies deserves special mention. Further sections deal
with the infrared spectra of crystals and high polymers (S.
Krimm) and of inorganic compounds (E. A . V. Ebswortlr).
The technique of infrared intensity measurements, which
becomes more and more important, and its application for
the determination of polarity are discussed by J. Overend. The
methods of dispersion measurements, including the practically important technique of attenuated total reflection, are
described by J. Fahrenfort. The book then closes with chapters on hydrogen bonding and solvent effects ( H . E. Hallnm)
and on infrared emission spectra ( W. C. Price). The text is
supplemented by some 800 references.
The editor has succeeded well in coordinating the contributions from the individual authors into a largely homogeneous
book with an up-to-date selection of themes. On account of
its admirable didactic qualities, it is recommended in general
as a textbook of spectroscopy for the advanced specialist and
for those striving to attain this status, for it teaches the reader
to think in spectroscopic terms. The outlay and print of the
book are exemplary in their clarity.

Infrared Spectra of Inorganic and Coordination Compounds.
By K. Nnkamoto. Sohn Wiley & Sons, Inc., New YorkLondon 1963. 1st Edit., XI1 324 pp.. numerous illustrs.
and tables, linen E2.12.0 (about $7.25).
There has long been a lack for a book reviewing the greatly
increased literature on vibrational spectra of inorganic compounds and giving a critical appraisal of publications in this
field with regard to both the practice of spectroscopy (e. g.
for structural analysis) and the theory of molecular physics
as related to force constants. The author attempts to satisfy
this need, to assign the published data to normal vibrations,
and to interprete their significance for the structures of molecules and ions. The first of the three sections of the book
(63 pp.) gives a brief but lucid discourse on the theory of spectra. In the second part (69 pp.), the spectra of simple organic
compounds are discussed, again very briefly. In the large

third section; which forms the maiiipart of the book, data for
inorganic complex compounds are desciibed. Five appendices
(45 pp.) include infer d i n tables of point groups, F and G
matrix elements of model cornpounds, and, by way of an
example, the complete normal coordinate analysis of an acetylacetonate. The text is supplemented by numerous tables,
illustrations, and literature references.
On account of the expansiveness and ready surveyability of
the material and its intelligible presentation, the book could
be warmly recommended to inorganic chemists interested in
spectroscopy and especially to complex chemists, if the author
had only discussed the material (particularly in Part 11) with
greater criticism. For example, in contrast to the data given
Oil p. 7 I, hydrogen halides (except for H F ) d o not associate in
the condensed phase; this follows from the fact that the vX-H
frequencies of liquid hydrogen halides are lower by 2-3X
than those of the gaseous compounds. It does not follow from
the appropriate spectra that there are “essentially covalent
bonds” in AgCN and AuCN (p. 73); the high CN frequencies
indicate only the presence of Ag..CN-..Ag.CN,.. bridges (or
Au). A free U O l 3 ion (p. 77) cannot be observed, according
to more recent publications; ligands are always coordinated
i n the plane vertical to the UOz axis, Results dating from 1938
are given for HzSe and DzSe (p. 831, although more recent
measurements (Palik, 1959) with some remarkably great
differences in frequencies are available. NT3, PT3, and AsT3
(p. 84) have never been measured, but were only calculated.
The Czv structure given for N2FZon p. 102 has been shown
to be incorrect; the compound is subject to geometric isomerism. The numerical values given for CH4 and CD4 (p. 104)
are not up-to-date. The data for NH4CI (p. 104) are not characteristic of the NH4@ion, because v4 (1400cm-1) here is
strongly split by Fermi resonance. Insufficiencies of this kind
are easy to eradicate in a new edition, and it would also be desirable for the author to go deeper into the relations between
spectra and molecular structures (a. g . how t o derive information about the bond order from the force constants). Sufficient space can be made quite easily by omission or reduction
of some figures [e. g. on pp. 74, 94, 147, 170, 174, and 200).
All in all, the book is usefull for thecritical, well-informed
reader; the outward appearance and the print are good.

Inarganic Thermogravimetric Analysis. By C. Duvof. Translated from the French by R . E. Oesper. Elsevier Publishing
Co., Amsterdam-London-New York 1963. 2nd Edit., XV +
722 pp., 77 figs., linen ca. D M 67.- (about S 17.00).
The principle of thermogravimetry is the continuous registration of alterations in weight of a solid sample during a heating program. Thanks to the development of modern automatically recording thermobalances, this process is easy and
rapid to execute and is a versatile aid in the investigation of
i9organic compounds: determination of moisture contents
and water of crystallization, controlled drying to constant
weight, testing of analytical precipitates for their suitability
for gravimetric estimations, detection of the limits of stable
phases, quantitative analysis based o n the loss of weight
during decomposition reactions (even of two components of
a mixture), investigations of reactions between solids and
gases, etc
Duvcil has compiled the first extensive monograph on this
field, in the development of which he has himself taken a
significant part. I n the first section of the second edition
(164 pp.), following a historical introduction, the apparatus
and experimental methods of thermogravimetry are dealt
with. This part has been extended by aboul 100 pp. in comparison with the 1953 edition, owing mainly to the description
of the automaticalIy recording thermobalances which have
been developed in the meantime and which are now commercially available. The main section of the book (519 pp.) contains the results of thermogravimetric investigations of analytical precipitates from 78 elements, arranged according to
increasing atomic weight. In all, the behavior of about 1200
