hypotheses. The one real feature whose absence will be felt
is a reference to the chemo-osmotic theory of oxidative
phosphorylations. Actual mistakes are neither frequent nor
significant. Particular mention is due t o the exceptionally
neat and faultless presentation, combined with the very
acceptable price. Every student interested in this (alas all too
often neglected) subject will be able to afford the sound
information contained in this excellent volume.

Mass Spectrometric Analysis of Solids. Edited by J . Ahenrn.
Elsevier Publishing Comuany, Amsterdam-London-New
York 1966. 1st Edit., viii, 175 pp., 46 figures, 13 tables,
Dfl. 30.-.
As a result of its high sensitivity, the simplicity of handling
samples, and the relative ease of interpreting spectra, mass
spectrometric analysis of solids is finding ever-increasing
fields of application. The present book, which comprises five
chapters written by experts, provides a review of the present
state of this field.
Chapter 1, by A . J . Ahearn, gives a general introduction t o
the subject. In Chapter 2, R . E. Honig treats the methods of
ion production used in analysis of solids. Methods of
evaluation and analytical errors are also dealt with insofar
as they are affected by the type of ion source. The use of
photographic plates in quantitative mass spectroscopic
analysis is decribed by E. B. Owens in Chapter 3, in which the
blackening process, properties of photoemulsions for ion
detection, density measurements, and methods for quantitative
evaluation of spectra receive a critical treatment. Chapter 4,
by J. W. Guthrie, deals with special analytical processes and
mentions investigations of liquids, organic substances, metals
of low melting point, as well as insulators and powders of
varying conductivity. Further, the application of standards
and measurements on very small samples are treated thoroughly. In thelast Chapter, W. M . Hickam and G . G. Sweeney
describe the application of the mass spectrograph as a
microprobe. In such work the surface of the sample is
examined by means of a tungsten tip, which serves as a
spark electrode. There is also a short section dealing with the
use of negative ions for analysis - a subject that is all too
often neglected.
The text is written clearly and concisely, and apart from
providing a general introduction it contains a wealth of data,
in the form of tables and diagrams, that will also be of value
to the expert. The bibliography at the end of each section is
also useful. The book can be recommended to all who are
concerned with analysis of solids, and particularly with trace
analysis, as well as to all libraries frequented by chemists

Spectrometric Identification of Organic Compounds. By R . M.
Silverstein and G . C. Bassler, John Wiley and Sons, New
York-London-Sydney 1967, 2nd Edit., IX, 256 pages,
numerous illustrations, 75 s.
The publication of the 2nd edition of Silverstein-Bassler in
1967 follows four years after that of the 1st [I]. The aim and
presentation remain unaltered, but the text has been completely rewritten, the exercises revised and supplemented, and
numerous new figures, tables, and literature references inserted. Thus, practically all the shortcomings of the 1st
edition have been eliminated. It is only difficult to understand why the UV bands are still denoted by the out-ofdate system of Burawuy and why in the compilation of the
notations for the aromatic bands it is precisely those of CIar
and Plutt that are missing.
In view of the increasing importance attached to physical
methods in organic chemistry today, the trouble taken by the
authors in preparing the 2nd edition is extremely welcome.
Chapter 2 (Mass Spectroscopy) has been considerably exAngew. Chem. internut. Edit. VoI. 7 (1968) / No. 5
panded. All mass spectra are now shown graphically (instead
of in tabular form as previously), so that typical spectra are
much easier to recognize. Chapter 3 (IR Spectroscopy) clarifies
the discussion of characteristic group frequencies of individual
classes of compounds by reproducing more than 40 typical
spectra. Chapter 4 (NMR spectroscopy) contains new sections dealing with protons on heteroatoms, coupling of
protons with other nuclei, more complex spin-spin coupling,
chemically but not magnetically equivalent protons, effects
of an asymmetric center, virtual coupling, vicinal and geminal
coupling in rigid systems, long-range coupling, and spin-spin
decoupling.
In all chapters the data has been expanded and supplemented
t o such an extent that this excellent guide t o identification of
spectra will serve not merely as a text-book and exercise book
but also as a quick reference source for the organic chemist
in his laboratory. The book can be recommended without
reservation t o all who wish to learn about the application
of spectroscopic methods to structural problems in organic
chemistry, and t o those who use spectroscopic methods in
their research.

Organic Chemistry of Synthetic High Polymers. By R . W .
Lenz. Interscience Publishers, a Division of John Wiley &
Sons, New York-London-Sydney, 1967. 1st Edit., xvi,
837 pages, 120 s.
This book attempts for the first time t o present the entire
field, including up-to-date results, in very concise and clear
form. I n principle the attempt has succeeded. Having regard
to the vast amount of material covering such a wide range of
topics, it would have succeeded even better if more than three
of the chapters had been written by specialists. Some of the
chapters are very short and assume considerable knowledge.
To compensate, the most important literature references have
been included - though only a few Russian ones - enabling
the original works t o be studied.
A number of detailed objections may be raised, of which the
most important are the following: The gain recorded by the
new systematic classification of polyreactions (1.1 -1.3) over
older concepts is outweighed by the future confusion that will
arise, particularly for the non-specialist. The chapter dealing
with inorganic polymers (6.6) leads to a wrong emphasis by
omitting the most important classes. The degradation of a
cationic chain end with an anion (9-15, p. 245) is much more
like the degradation of a n anionic chain end with an electrophilic group than a radical recombination (9-13, p. 245).
A p-elimination (9-16, p. 245) does not represent a disproportionation. By contrast to anionic end groups, the
degradation reaction on free radical end groups is governed
by the probability of the collision of two chain ends, i.e.
purely thermodynamically; the comparison between “living
polymers” and relatively stable radicals (cf. p. 247) is therefore not justified.
A great advantage of the book is the strict classification of
the material and the generally concise and clear style. The
references t o model reactions involving species of low molecular weight that are given for many polyreactions are
extremely useful and the frequent numerical examples given
with the formulas contribute much t o the clarity of the book.
This welcome new publication undoubtedly enriches the
literature in this field and will find a wide readership.
