maximum clarity, but it has also been necessary to include
reports o n the revolutionary progress made in classic processes. We find, for example, that the ammonia process has
changed fundamentally in the last decade. Petrochemical
synthesis gas production has become established, new catalysts allow almost complete CO conversion at low temperatures, and with the development of the turbocompressor
there has been a transition to a single-line plants with capacities of 1000 t/day.
In addition to the varied scientific and technical developments reported in this volume, particular mention should be
made of the article o n the development of science, which
gives a n impressive picture of the dynamics and importance
of technological chemistry. The global chemical production
has quintupled in the last twenty years, and will continue to
increase at this exponential rate. The pipeline network for oil
and petrochemical products amounts to 40 times the circumference of the earth and is increased by 15000 to 20000 km
a year. Between the years 1958 and 1968 the world production
of synthetic fibers increased ninefold. In contrast to other
large industries, the chemical industry deals at the same time
with the production of basic substances, intermediates, and
consumer articles. Unlike any other industry, it acts both as
a supplier and as a purchaser in all fields of the economy, and
is thus perpetually involved in the development of human
relationships and social life. With its abundant key figures,
this article gives a clear survey of development trends.
In view of this dynamism one may well wonder to what
extent a field subject to such far-reaching changes can be
covered by an encyclopedia. In fact, the achievements and
difficulties of our scientific and technological development
are mirrored in the achievements and problems of the present
Ullmann Encyclopedia. A characteristic of our time is that
the quantity of information increases more quickly than it
can be arranged and classified. New documentation systems
are being developed so that we can remain masters of this
situation and store information in readily available form.
Electronic information services, however necessary and important they are, can only store material; they cannot sift
through it, evaluate it or select what is important - they
cannot process (reduce and compress) the information. The
more quickly a field changes and grows the more important
the condensation of material becomes, so that a survey of
trends and developments is available. If there is no overall
survey, contact and understanding between allied branches
are lost and hence also the possibility of fruitful cooperation.
Furthermore, difficulties will be created if this welter of
material is handed down in disorder to the next generation.
There is little point in supplying students with the newest and
most up-to-date information - it will be out of date by the
time they are ready to use it - but there must be a comparative penetration of the material so that the essential principles,
which will play a decisive role in development, can be worked
out. A large number of our educational difficulties arise
because we neglect the didactic processing and condensation
of knowledge in the process of searching out new material. In
the case of many students this leads not only to difficulties in
understanding but also to misconceptions and highly undesirable attitudes t o this complex of modern chemical
practice which is so important for our very existence.
Ullmann can be considered as a comprehensive personal
interpretation of chemical technology and the chemical
industry; it is an example of the fact that abstract modern
theory can successfully be shown to have relevance to the
accepted formulas already used in practice. It is written in
such a way that anyone can obtain information on the main
aspects of a related field in which he is not at home. Finally,
therefore, we must thank the authors who have taken the
time, for the most part in spite of pressing practical duties, to
describe their work to a wider circle of colleagues, and in
particular the management and editors who have managed
to coordinate all this work and produce a n encyclopedia
which, as its name implies, deals coherently with the whole
sphere of chemical and technological knowledge.

The Wave Mechanics of Atoms, Molecules and Ions. By C . J .
H . Schutte, Edward Arnold (Publishers) Ltd., London

84 s.
Many of the modern textbooks devoted to the subject of
wave mechanics and molecules suffer from the disadvantage,
in particular as regards the chemistry student, of assuming
either a very extensive or a very meager knowledge of mathematics o n the part of the reader. Consequently, the understanding of the chemical bond is often inadequate.
The present book attempts to tread the middle path, and in
fact the author does succeed in striking a happy medium between the two extremes.
The book consists of three main parts, the first of which deals
with the principles of wave mechanics. Numerous examples
are given starting with classical mechanics. Perhaps it was
not entirely necessary to include Bohr’s postulates, which
have now passed into history and which have been extended
by wave mechanics. On the other hand, the reviewer finds it
it highly sensible to present the fundamentals with the aid of
operator algebra. The perturbation method is discussed at
length.
The second part consists of a total of 11 sections in which the
individual methods of quantum chemistry are dealt with:
First of all a particle in simple potential fields, then the
harmonic oscillator in its application to spectroscopy. Rotational and vibrational states are considered next. The 5th
section deals with the hydrogen atom, and the 6th with polyelectronic atoms. Sections 7 and 8 are devoted to group
theory and, finally, the last three sections are concerned with
di- and polyatomic molecules and with a number of applications of the Hiickel theory.
The third part of the book deals exclusively with spectroscopy. An introduction to the principles of spectroscopy is
followed by a discussion of the spectroscopic behavior of
rotational states, vibrational states, and finally, of complex
compounds, including magnetic effects.
Exercises are given with each section, the solutions being
collected at the end of the book. There is also an appendix on
symmetry groups.
The book is clearly written, well illustrated, and provided
with a very detailed subject index. It can be emphatically recommended to every student of chemistry. Even those who
merely want to acquaint themselves with the field will find it
to be a n excellent introduction.
