Book Review An Introduction to the Chiroptical Methods in Chemistry. By P. Crabb

that the authors are approaching the chemistry of metalolefin complexes primarily from the standpoint of the
organic chemist, which will undoubtedly please a wide
readership.
As to criticisms, the reviewer was surprised to find almost
more on metal-ally1 complexes than on metal-olefin
complexes in a book with the above title. A longer and
more detailed title would have been better. Another
notable shortcoming is that though the relationships
between olefin and ally1 complexes are rightly emphasized,
there is no reference to similar relationships between
olefin and aromatic complexes (e.9. between C,H,ML,
and [C,H,ML,]+, C,H,ML, and [C,H,MLn]+). The
discussion of the extremely interesting olefin-metal compounds with “fluctuating structures” is also much too
short.
Despite these objections, the monograph, which is a true
pocket book, fulfills its purpose. It is recommended in
particular to those who wish a general picture rather
than special information and who are interested in particular in the use of organometallic complexes fonsynthetic
problems.

An Introduction to the Chiroptical Methods in Chemistry. By
P. Crabbk. P. de Aguinaco, Mexico 1971.1st edit., 121pp.,
54 figures, 16 4.00.
P. CrabbC, who has also written an extensive monograph
on the same topic, here presents a brief introduction to
chiroptical methods (circular dichroism (CD) and optical
rotatory dispersion (ORD)). Of course, it cannot be regarded as a substitute for a detailed textbook, but is a means of
bringing oneself up to date with the recent literature, using
the index which is arranged by chromophores. After a brief
description of the fundamental concepts, the individual
groups capable of bringing about a Cotton effect are enumerated, together with the more important rules applying
to them; a critical comparison is lacking here. The topic of
biopolymers is not dealt with in quite so much detail, but
the book does include details on both inorganic complexes
and the Faraday effect. This small book, which is printed
on extremely hard-wearing paper, contains an extraordinary wealth of literature references, which actually extend
into the early part of 1971 and is thus a valuable addition
to this branch of spectroscopy which up to now has received only sporadic attention.

Messung radioaktiver Nuklide (Measurement of Radioactive Nuclides). By K . Biichmann. Verlag Chemie
GmbH, Weinheim/Bergstr. 1970.1st Edit., xii, 187 pp.,
194 figures, 30 tables, bound DM 58.--.
This book is a comprehensive account of methods for the
detection of nuclear radiation. It provides the scientist,
the engineer, or the student with a detailed guide to the
execution and evaluation of radioactivity measurements.
Numerous measuring arrangements and methods for this
purpose are described, and their usefulness for the solution
of particular measurement problems is assessed.
The layout and arrangement are very clear. The first few
chapters describe the construction of radiation detectors
Angew. Chem. internat. Edit. 1 Vol. 11 (1972) No. I
and the interactions of nuclear radiation with matter
that are necessary for an understanding of the detectors.
A chapter on electronic aids unfortunately deals mainly
with tube circuits (cathode follower, coincidence stage,
Schmitt trigger) and omits the transistor circuits that are
now in common use. This is followed by detailed chapters
on the detection of the various types of radiation and the
determination of their energy. A useful section is included
for practical workers on the evaluation of y spectra. A
chapter on the relationship between count rate and activity
is important to the evaluation of results. The book ends
with practical advice on measuring arrangements, standard
preparations, and the dosimetry of nuclear radiation.
The practical value of the (relatively expensive) book is
enhanced by bibliographies to the various chapters and a
reliable subject index.

1971, vi, xiii, 451 pp., 32 figures, bound. DM 532.-.
Together with gold, silver, and copper, tin is one of the
first few metals used by man. The first chapter of the
present volume is a 172-page presentation of the history
of tin, and at the same time is a form of cultural history
of the last five millenia, woven around the use of this
metal. Although this undoubtedly makes interesting
reading, it would seem to the present reviewer that it is
extending the scope of this chapter too far to devote
several pages to the origin of the name of the element, and
finally to consider the problem of whether the Publius
Crassus mentioned in a report by the geographer Strabo
(of Amasia in Pontus) was the younger son of the member
of the 1st triumvirate, who subdued Aquitania under
Caesar in 57 BC, or whether he was the Spanish proconsul
in 97 BC, although it is not known whether the latter
“undertook any exploratory travels”. This is not to
criticize the presentation of the history of tin, which
among other things contains many detailed quotations
from ancient sources that are not readily accessible, but
only to ask whether this amount of detail in a handbook
of inorganic chemistry, which in general will only be
consulted by chemists and representatives of closely
allied disciplines, is not paid for at too high a price. There
is no doubt that the presentation would be of interest
to a very wide circle of readers. The present reviewer would
therefore suggest that such detailed historical presentations
should in future be published as separate volumes, which
could be offered to a much wider circle of readers, with a
possible reduction in cost.
After the sections on names and symbols, tin in early
cultures, tin in east Asia, India, Africa, America, and tin in
the Arab civilization, there are sections concerned with
tin ores and their extraction and processing. Detailed
descriptions are given of tinning processes, particularly
with regard to the manufacture of tinplate. Special attention
is given to the various regions where the tinplate industry
