space analysis is deliberately omitted and the reader is referred to the book by Hachenberg and Schmidt. The authors devote the last two chapters to the quantification and
evaluation of chromatograms and to the preparation of
standard gas mixtures. For the latter they limit themselves
to a brief review of the various methods and techniques for
the preparation of mixtures of gases and their critical assessment.
The book includes an extensive reference list in order of
authors’ names (172 references), which includes publications up to 1981. Additionally an appendix includes publications from the years 1981 and 1982 (19 references).
A point worthy of criticism is the plethora of units
quoted. With Anglo-American nonchalance and uninfluenced by IUPAC recommendations or even SI regulations, pascals, pounds per square inch, atmospheres and
metric and imperial units of length are quoted alongside
each other. This will, however, not present any difficulty to
the analyst who practises gas chromatography every day.
This book is written for the man at the bench. It is easy
to read, comprehensibly laid out, and easy to understand
even for the reader whose native language is not English.
There are almost no printing errors. Within its compass of
140 pages the book contains a wealth of information,
which will be of great use to the reader who is acquainted
with the basic principles and practice of gas chromatography in helping him in his choice of apparatus and in the
analysis of complex mixtures of gases.

Atomabsorptionsspektrometrie. By B. Welz. 3rd completely
revised edition. Verlag Chemie, Weinheim 1983. xiii, 527
pp., bound, DM 128.00.
Almost every new edition of a scientific or technical
book is offered to the reader as being “completely revised”. During the period of eight years between the publication of the second edition“] and the present third edition
atomic absorption spectroscopy has undergone a great
deal of development. The basic principles of AAS remain
unaltered, but general knowledge has been greatly augmented through the large increase in the application of this
analytical technique. A really “new” book must combine
the old basic knowledge with the new developments, additional fields of application, and also a critical description
of the method. Welz has attempted this in the new edition
and seems to have succeeded well. The wealth of material
has almost doubled the size of the book; the number of figures has been enlarged from 73 to 140, the number of tables has only been slightly increased from 46 to 51. The
real extent of the enlargement of knowledge, however, is
best seen in the additional 1103 references; the total is now
2491. The increase demonstrable in these numbers is sufficient alone to justify the publisher’s claim of “complete revision” of this book.
The additional figures are particularly welcome, both in
the sections covering the basic principles and in those
dealing with interferences. The clarity is significantly improved in both cases. The beginner receives an easier entry
into the basics of the subject. Those who are already famil[“I

iar with the problems of AAS can estimate the real extent
of interferences much better with the aid of the diagrams.
The methodic layout of the volume is very similar to that
of the previous edition. The chapters are naturally somewhat longer, but neatly tailored to accommodate the newer
methods. A short introduction is followed by a brief, but
adequate, description of the radiation sources in use
nowadays (eg. HCL, EDL). The chapter on atomization
techniques includes the flame technique, the graphite furnace technique, the hydride and cold vapor techniques.
The author deals both with the basic theory and with the
current design of apparatus for each method. The historical outline of the techniques and further reference to specific techniques convey not only topical hints but a general
picture to the reader with a greater interest in AAS. Concisely constructed chapters on optics and detection and
output give an insight into spectrometer structure. Since
most users of AAS d o not wish to rebuild their instruments
a short treatment here is appropriate. A great deal of space
is devoted to interferences in AAS. They are described in a
separate chapter, but also in the detailed section “Techniques of atomic absorption spectroscopy”. This indication of the many possibilities of interference can be of
great help to the practitioner in avoiding systematic errors
in his determinations. A great deal of space in this context
is devoted to the hydride and cold vapor techniques, where
even today the interferences often constitute unresolved
problems. The third edition too contains the indispensable
descriptions of the individual elements. For each element
the description of the standard conditions is followed by
allusion to the various sources of interference. Although
only a minority of possible interferences can be covered in
such a section, it will certainly be of help in avoiding a
multiplicity of the more usual errors.
N o matter what its length the chapter devoted to specific
applications is, considering its aims, of necessity too short.
This deficit is made up for here by the large number of references to specific applications in the original literature.
“Welz” is the only German-language book dealing with
atomic absorption spectroscopy. The 3rd edition can be
understood both as a textbook and as a laboratory handbook. It can provide both the interested laboratory technician and the experienced practitioner of AAS with a profusion of practical advice and a deeper understanding of the
method.

Transition Metal Carbene Complexes. With contributions
by K . H. DOt2, H. Fischer, P. Hofmann, F. R . Kreissl, U.
Schubert, and K . Weiss. Verlag Chemie, Weinheim 1983.
xiii, 264 pp., bound, D M 120.00.
This book is dedicated to Professor E . 0. Fischer and is
written by some of his more recent senior co-workers in
honor of his 65th birthday (November 10, 1983). The
theme of the book relates to a n area discovered by the dedicatee in 1964, and has been a principal preoccupation of
his group in the intervening years. Hence, the appropriateness of the topic and the selection of the contributors is to
be commended.
The book is attractively produced. Details of its chapter
headings are as follows. 1. The Synthesis of Carbene Complexes (H. Fischer), 66 pages, 476 refs.; 2. Spectroscopic
Properties of Transition Metal Carbene Complexes (H.
Fischer and F. R . Kreissl), 1 pages, 12 refs.: 3. Solid State
137
Structures of Carbene Complexes (U.Schubert), 37 pages,
159 refs.; 4. Electronic Structures of Transition Metal Carbene Complexes (P. Hofmann), 35 pages, 55 refs.; 5. Metal
Complexes from Carbene Complexes : Selected Reactions
(F. R . Kreissl), 37 pages, 174 refs.; 6. Carbene Complexes
in Organic Synthesis ( K . H . Dotz), 34 pages, 88 refs.; 7.
Carbene Complexes as Intermediates in Catalytic Reactions ( K . Weiss), 18 pages, 75 refs.; 8. Mechanistic Aspects
of Carbene Complex Reactions ( H . Fischer), 16 pages, 76
refs. It is somewhat unexpected that there should be no
subject index.
In the Preface, the authors indicate that their aim is to
identify principles rather than to attempt to provide a comprehensive coverage of the field. No doubt it is right that
they should concentrate their attention on what are now
known generally as Fischer-type carbenemetal complexes,
that is to say, they devote the majority of their detailed attention to complexes of the type [M(CO)5(CRR’)],in which
M = C r or W, R is an alkyl or aryl group, and R’ is a n-electron-donor group such as methoxy or amino. In most
chapters there is no indication of the literature cut-off
date; but Professor Schubert, who incidentally does provide a comprehensive table of data on structures (150 in
all), states that his bibliography coverage ends with September 1982.
The authors are, of course, experts in their fields. Therefore, it is not unexpected that they write with authority.
Two chapters seem less good than might have been anticipated. To cover spectroscopy in 1 pages and in so doing
ignore a topic such as the rotational barrier around the metal-carbon bond is surprising; and, moreover to have references, which with two exceptions (1974, 1977) terminate in
1972 is also curious. The section dealing with carbene
complexes as catalytic intermediates could quite well have
been omitted, in the light of the rather low level at which
the discussioni is pitched, and the existence of superior reviews of this topic.
This book is clearly to be welcomed, particularly as a
useful summary of some of the major achievements in this
field of the Munich group. It will be of considerable value
to other workers elsewhere; although they might well have
preferred a more comprehensive coverage, with perhaps a
somewhat different balance.
E. 0. Fischer’s achievements in organometallic chemistry are, of course, outstanding. This book gives readers an
opportunity to reflect how, in only one of his major areas,
a vast amount of current chemistry can be directly traced
back to his initiatives. Furthermore his skill as a teacher
has obviously been transmitted to many of his coworkers.
