Low-Energy Electrons and Surface Chemistry. Monographs
in Modern Chemistry 4. By G . Ertl and J . Kiippers. Verlag
Chemie, GmbH, Weinheim 1974. 1st Edit., x, 251 pp., 152

The authors’ objective for this monograph was to provide
the non-expert with a readily understandable introduction
to the most important methods used in the chemistry and
physics of solid surfaces. This objective has been excellently
achieved, within the limitations that the auth&s imposed
on themselves, but the book may also prove useful to experts,
particularly because of the detailed literature references added
to each chapter. The limitations mentioned result in a preference for practical applications, with omission of a detailed
presentation of the theoretical fundamentals and the omission
of-also important-methods of investigation in which slow
electrons d o not take part (e.g. SIMS, ion back-scattering,
RHEED). The latter is a disadvantage.
The main emphasis of the book is in the 60 pages that
make up Chapter 9 (Low-Energy Electron Diffraction =
LEED). This is preceded by chapters on the methods that
are usually termed “supplementary techniques”, among which
Chapter 2 concerning the important topic of Auger electron
spectroscopy occupies the largest space (33 pages). Secondaryelectron, photoelectron, and X-ray excitation spectroscopy
(APS) and the problems of the work function are treated
more tersely. Field-emission and ion-neutralization spectroscopy, and also phonon effects on surfaces, are treated only
very briefly,
Chapter 11 (the last) which deals, unfortunately rather too
shortly, with the application of methods previously discussed
to problems of adsorption is particularly impressive. This
makes it clear that only a suitable combination of many
different techniques, if possible in the same UHV apparatus,
is at present able to provide tenable statements about a d s o r p
tion processes on crystal surfaces. One gets the impression
that some of the individual problems discussed in Chapter
11 should have been treated in more detail in special chapters.
O n the other hand, the brief presentation is advantageous
for an introductory text, and the interested reader can find
moredetailed information in the extensive literature references.

Natural Products Chemistry. Vol. 1. Edited by K. Nakanishi,
7: Goto, S. Itb, S. Natori, and S. Nozoe. Kodansha Ltd.,
Tokyo/Academic Press, Inc. New York-London 1974. 1st
Edit., 562 pp., bound $ 32.50.
The chemistry of natural products has undergone a renaissance in recent years, though unfortunately not in Germany.
The intention of the well known Japanese publishers was
that this, the first of two volumes planned to cover natural
products chemistry, should fill a gap between textbooks of
organic chemistry and special presentations of more restricted
fields of natural products chemistry. The introductory chapters
on the classification of natural products and on physicochemical data are followed by four chapters on mono- and sesquiterpenes, diterpenes, sester-, tri-, and higher terpenoids, and
steroids. The emphasis of the presentation is on a wealth
of clearly arranged formulas that permit rapid orientation
in the subject. The brief accompanying text contains information on structure elucidation, syntheses, reactions, and biosynthesis as well as data on origin and physiological action.
In respect of biosynthesis, however, little is included about
work on the enzymic aspects. Physicochemical data are given
for each compound including the position of the most important proton-resonance peaks.
The book contains an enormous amount of information,
special consideration being given to the newer literature up
to 1973. Classical work on structure determination is reported
only in the steroid chapter. This textbook could be a most
valuable source of information to the natural products chemist,
but it is also suitable for the preparation of lectures to students
and symposia, since the structural formulas are so arranged
that they can be used directly for the preparation of diapositives. Furthermore, the chemist active in other fields can
certainly be stimulated by the many synthetic methods
illustrated. The second volume is awaited impatiently, but
it is not too early to wish the book a wide readership.

Recent Analytical Developments in the Petroleum Industry.
Edited by D. R. Hodges. Applied Science Publishers Ltd.,
Barking 1974. 1st Edit., IX, 337 pp., 109 figs., 56 tables,
bound, E 10.-.
This volume contains the text of lectures given at a symposium organized by the Institute of Petroleum in London,
together with the relevant discussions. There are 19 contributions, opened by A. S. Curry who reports on the progress
in analytical chemistry during the last 10-20 years. Subsequent chapters of the book are devoted to special methods
of analysis of hydrocarbons and additives; each of these
chapters gives a critical review and a comparison with similar
methods and marks out the limits and possibilities; critical
remarks at the discussions, often kept very short, round off
each theme.
J. P. Coates compares the possibilities of IR spectroscopy
and laster Raman spectroscopy. The section by D. E. Hillmun,
7: J . Paul, and D. G. Cobbold is devoted to the determination
of corrosion inhibitor Hitec E 515 in aircraft fuel by gel
