may be worth the experience to be presented the familiar onedimensional free-electron model from quite a different point
of view under the unusual name of “reflection oscillator”.

Einfiihrung in die Chromatographie (Introduction to Chromatography). By H . Hrapin. Wissenschaftliche Taschenbucher (Scientific Manuals), Vol. 30. Akademie-Verlag,
Berlin 1965. 1st ed., 236 pp., 32 illustrations, 12 tables,
paper S 8.00.
More or less comprehensive monographs on the various
types of chromatography, e.g. paper, thin layer, and gas
chromatography, already exist. However, until now there has
been no German-language “Introduction to Chromatography”, so that the 236-page book from the WTB series
fills a gap. The author has a lucid style, and knows how to
present even difficult ideas in a comprehensible manner. The
subdivision is almost too rigid, so that the beginner may
overlook the common feature of all these processes. However,
a clearer separation of the actual types of chromatography
from the numerous operating techniques is desirable. An
introductory “Classification” is followed by a 44-page discussion of the theories of chromatography, the mathematical
treatment of the plate theory being given more space than is
necessary. The section o n the “Practice of Column Chromatography” (45 pp.) is very successful The next-largest section
(37 pp.) is that on gas chromatography. A striking feature
here is that details are given for the construction of detectors.
23 pages are devoted to paper chromatography, and 13 pages
to thin-layer chromatography. Electrophoresis is discussed
rather too briefly in 7 pages. References to companies are
mainly confined to manufacturers in East Germany. For
a second edition, the reviewer ‘would like to see a more
international character also in this respect.
On the whole, the book fully achieves its purpose, i.e. to
introduce the beginner to the various and versatile possibilities of chromatography. It presents a good survey of the
field. It can only be hoped that it will lead, not only to the
use of one of these methods, but to their rational combination.

Synthetic Methods of Organic Chemistry, VoI. 20, by W.Theilheimer. Verlag S . Karger, Basel-New York 1966. 1st Edit.,
xiv, 740 pp., sFr 246.00.
The present volume of this well-known series continues to
report o n modern synthetic reactions in the proven manner.
702 well-chosen articles from the period 1963-1965 cover the
entire field of organic chemistry. In view of the growing
importance of stereospecific reactions and photorea-ctions,
more space is devoted to these topics. Numerous reactions
for the synthesis of complicated isocyclic and heterocyclic
ring systems are also included. To limit the volume to a
reasonable size, synthetic work that has nothing new to offer
with regard to method is omitted. However, the articles in
earlier volumes are brought up to date by the list of “Supplementary references” (17 pages).
This comprehensive volume concludes the series 16-2C, and
accordingly contains all the references of volumes 16-19 in
the text and in the index. This index (148 pages) will be
welcomed by all who cannot become accustomed to the
system of arrangement used throughout the series. The value
of the collection is increased by the inclusion of new entries
such as “prevention” and ‘‘retention” of f u ~ c i i o n a lgroups.
The four pages on important developments in organic
chemistry in 1965-1966 are particularly useful.
This series, whlch was launched some time ago, no longer
requires special recommendation. However, it occurs to the
review2r that the a supplementary peep-hole index might be
a useful aid t o the retrieval of the information collected in the
20 volumes of this work.

The Penicillin Group of Drugs. By G.T. Stewrrrt. ElsevieiPublishing Company, Amsterdam 1965.1st ed.,xii, 21 2 pp..
11 illustrations, bound Dutch fl. 27.50 (cn. $ 7.50).
Penicillin, originally the name of a n active p;inciple rather
than of a definite substance, not only formed the starting
point for antibiotics research in general, but also became il
collective term for a group of drugs long after its first investigation. The author’s description of this development i n
the first three chapters shows a great deal of detailed knowledge. This part of the book presents interesting information
about the history of medicine, though it is not exhaustive.
particularly in relation to non-British contributions.
The next five chapters deal with the semi-synthetic penicillins.
mainly from the point of view of application. Chapter Y
discusses morphological and biochemical aspects of the mode
of action, and the chemical aspects are discussed i n Chapter
10. It would have been better if, e.g.. of the six structural
formulae on page 100, at least one had been correct, and i f
C-2 of the penicillin skeleton had not been trivalent throughout the book. The general cofidusions on the mode of
action (Chapter 11) are very cautious. They are intended to
show how far away we still.are from a n understanding of the
relationships Though the pharmacology and toxicology of
some penicillins have already beev cons’idered, these and the
problems of tesistance and allergy are again discussed in
three further chapters. The book closes with the epidemiologic importance of the penicillins and a brief discussion of the
cephalosporins.
The book was not written for the organic chemist, but microbiologists, physicians, and pharmacists will find some
fundamental information in it. Care has been taken with its
presentation, and the index and reference lists are comprehensive.

Theories mofeculaires de la Resonance Magnetique Nuclkaire.
Applications B la chimie structurale. (Molecular Theories
of Nuclear Magnetic Resonance. Applications to Structural Chemistry). By C . Mavel. Dunod, Paris 1966. 1st ed.,
x, 325 pp., 64 illustrations, 47 tables, paper F 78.- (cn.
$17.-).
In only a few years, high-resolution nuclear magnetic resonance gained an important place alongside other spectroscopic methods in chemistry. In the present book, G . Matel
reviews recent publications (subsequent to the book published
in 1959 by Pople, Schneider, and Bernstein) dealing with the
theoretical aspects of nuclear magnetic resonance with
special reference to the electronic structure of organic molecules. The obvious aim of the author was to provide a bridge
between theory and experiment in this rapidly developing
field for the chemist who uses nuclear resonance as an aid
in his work.
The two introductory chapters (20 pp.) on the interpretation
of nuclear magnetic resonance on the basis of the Bloch
equations and on the introduction of the chemical shift and
nuclear spin coupling, consequently, are short. In the section
on the chemical shift (60 pp.), the fundamental principles of
the perturbation theory and of the variation method are first
described, and the semi-empirical theories by means of which
the empirical data have so far been interpreted are then
discussed. A similar plan is followed in the chapter (34 pp.)
on indirect spin coupling. Unfortunately, the recent development of the theory by the molecular orbital method (Pople,
Santry, Both6er-By) is mentioned only briefly. The analysis
of nuclear resonance spectra (72 pp.) is carried out explicitly
for the simpler cases. Tables arc given for a number of more
complicated cases, and the moment method and iterative
methcxls are mentioned. This chapter also contains a discussion (unfortunately very short) of the spectra of oriented
molecules, which have recently attracted considerable attention. The book closes with chapters o n multi-quantum
transitions (10 pp.). the theoretical aspects of double reso-
