While the section “Quantum-Mechanical Calculation of the
Orbital Angular Momentum” has been added to the Appendix
in the translation, the references to more advanced and additional literature which are given in the English version
have^ unfortunately been omitted. The retention or the updating of these references would have helped to make the otherwise very readable book even more suitable for use as a basis
of, and as supplementary reading for, lectures on coordination

Die Analyse der organischen Verunreinigungen in Trink-,
Brauch- und AbwHssern [The Analysis of Organic Impurities
in Drinking Water, Water for Industrial Use, and EMuents].
By W Leithe. Wissenschaftliche Verlagsgesellschaft mbH,
Stuttgart 1972. 1st ed., xii, 172 pp., 21 figs., 22 tables, bound
D M 48.The investigation of impurities in water samples from trade,
Industry, agriculture, and the home is becoming increasingly
important. Owing to the extreme diversity of the substances
and agents with which water bodies are being increasingly
contaminated, it is often necessary to limit the investigation
to the determination of total contents of certain groups or
to use specific methods for individual substances that are
of special interest. In the present book the author tries to
provide the first survey of the very topical analysis of organic
impurities in water.
An introduction to the problems of the contamination of
water, biological self-purification in running water, and the
purification processes in clarification plants is followed by
a very detailed description of methods for the quantitative
estimation of classes of organic material. These include
methods for the determination of organic carbon, the potassium permanganate and bichromate consumptions, and the
biochemical oxygen demanc!. This is followed by a description
of analytical methods for groups of substances and individual
substances, such as fatty acids, cyanides, phenols, detergents,
nitrilotriacetic acid, hydrocarbons (benzines and mi,neral oils),
chlorinated hydrocarbons, pesticides, urea, uric acid, coprosterols, urochromes, humic acids, lignin and ligninsulfonic
acids, and 3,4-benzpyrene.
With this large collection of special analytical methods for
organic contaminants in drinking water, water. for industrial
use, and effluents, the book is a valuable addition to the
standard literature on water analysis, and can be strongly
recommended to all chemists concerned with the investigation
and assessment of water bodies.

Struktur und Reaktivitat polarer Organometalle (Structure and
Reactivity of Polar Organometallic Compounds). By M .
Schlosser. Springer-Verlag, Berlin-Heidelberg-New
1973. 1st Edit., x, 187 pp., 29 figures, bound DM 78.-.
This clearly and fluently written book deals with the structure
and reactivity of organometallic compounds of alkali and
alkaline earth metals. It is supplemented by a section on
C-H acidities, to which a very large amount of space (64
out of 187 pages) has been devoted.
Structures in the crystal lattice, the possible aggregations of
polar organometallic compounds in solution (from the dimers
resulting from association via electron-deficient bonds to the
compounds that are dissociated info metal cations and carbanions by solvation), and the connection between aggregation
and reactivity are described in detail. The sections on parameters that influence reactions and on the control of reactions
are particularly interesting.

Carefully chosen tables, e. y. the scale of “organometallically
projected” C-H acidities of hydrocarbons, as well as very
clear diagrams and a considerable number (447) of references
even to very recent literature further increase the value of
the book to the organometallic chemist who is more familiar
with the other groups of the periodic system.
The book unfortunately contains a number of traps for the
non-specialist and for the student; these traps are partly due
to the quantitative indefiniteness of the adjective “polar”, but
are partly also laid by the author himself when he writes
e.g. “the ideal case of an organometallic reaction is the carbanion process”. While reading this book it would be easy
to forget that it describes only one (extreme) aspect of organometallic chemistry, and the non-specialist could take the part
for the whole.
With and in spite of this reservation, this is a readable, very
stimulating book.

Techniques of Electrochemistry. Vol. 1. By E. Yeayer and A .
J . Salkind. Wiley-Interscience, New York-London
1st Edit., ix, 581 pp., various figures and tables, bound
L 11.70.
To forestall any misunderstandings, it should be stated that
this book is concerned exclusively with electrochemical experimental and measuring techniques in the laboratory. As stated
in the foreword, preparative methods and techniques for
electrochemical reactions and processes will be dealt with
in later volumes. Another peculiarity of this book, which
is understandable in view of its American orientation, is the
strong emphasis that is placed on the theoretical principles
and the detailed quantitative discussion of the measuring
methods described.
This is particularly noticeable in the first article, by R. G.
Bates, on equilibrium potentials. It is not until the last few
pages that the reader learns anything about the preparation
of reference electrodes. However, the instructions for the platinization of platinum electrodes are not precise and therefore
cannot be used, while the instructions for silver/silver chloride
and calomel electrodes are unnecessarily complicated. The
article by R. Payne on the electrochemical double layer is
much more balanced. The rigid double layer is also referred
to on p. 65 as the Perrin layer and on p. 72 as the Helmholtz
layer. The measuring methods based on the capacity of the
double layer, the surface potential, and voltammetry are described in detail, but almost exclusively for mercury electrodes.
A . Salkind describes the measurement of the true surface area
and the porosity of electrodes from a practical standpoint.
The predominantly non-electrochemical methods, which are
mostly described for the example of lead dioxide, can also
be found in books on catalysis.
The topical field of elect.rochemica1kinetics is finally discussed
in two long chapters. J . Kuta and E. Yeayer describe the
stationary and non-stationary electrical methods. The relationships from themercury drop electrode are discussed in particular detail. However, cyclic voltammetry is also touched upon.
The non-electrochemical methods are summarily dealt with
in the chapter by B. E. Conway. The emphasis here is on
optical methods. The article, which was completed in 1969,
naturally contains little information on fields such as ATR
spectroscopy that have developed rapidly only during the
past few years. Some parts of the article overlap with the
chapter by Payne.
The book is addressed to the electrochemist, who will certainly
welcome a review of measuring and experimental methods
in this field. The book contains no operating procedures.
Little importance is attached to experimental skill. For
