Atomic spectroscopy methods are nowadays the most important of the tools used in the analytical chemistry of the
elements. Their great variety, which one can now barely keep
track of, and the remarkably rapid pace of instrument developments in this field, already make it difficult for competent
users to evaluate these with regard to such criteria as detection capability, reliability and value for money, so as to be
able to solve analytical problems that are nowadays becoming ever more complicated.
The task of teaching young scientists the basic knowledge
required is especially difficult. In principle, therefore, any
attempt to make this easier by providing an up-to-date introduction to atomic spectroscopy, limited to the basic essentials, is appropriate and welcome.
The author of this book is an experienced spectroscopist
and analyst who has been involved in the rapid developments that have occurred in this area of applied analysis
since the 1950s, has made a name for himself through many
original contributions, and now teaches analytical chemistry
as a professor at the University of Louisiana, USA. He has
previously written several monographs on the subject and
chapters in handbooks, and is the editor of two specialist
This monograph provides further evidence of his competence. He has set out to provide, in about 300 informative
and richly illustrated pages, a picture of modern atomic spectroscopy, including the necessary basic physical background
and the analytical capabilities and limitations of the methods.

A compressed introduction to such a broad subject obviously requires tight restrictions on the choice of methods and
literature references. The textbook-style treatment is therefore limited to those methods of optical atomic spectroscopy
that are currently most important and are in routine analytical use, such as atomic absorption, emission and fluorescence spectroscopies and their most important excitation
sources, both classical and modern (radiofrequency plasmas).
However, this reviewer was disappointed at not finding at
least some references to the most recent, highly interesting,
developments in laser spectroscopy, which will revolutionize
atomic spectroscopy in the future. Also there should have
been some mention of microwave-induced plasmas (MIP)
and glow discharges (GD), which are very powerful modern
excitation sources for optical emission spectroscopy and
mass spectrometry.
Unfortunately, too, not enough detail is given of the many
different ways of reducing possible sources of error and improving detection capabilities by combining with appropriate chemical and physical methods of separation and enrichment, which are indispensable techniques in elemental trace
On the other hand, one could easily have done without the
extensive tables of wavelengths (20 pages) used for the determination of elements by flame AAS, since practitioners
already have access to adequate published tables, whereas
newcomers to the field are unlikely to find them interesting.
Also flame photometry is treated in too much detail in relation to its present importance.
Reading this book has again reminded the reviewer how
difficult it is to give, in a limited space, a balanced treatment
for teaching purposes of such an extensive and important
field as atomic spectroscopy has now become in modern
elemental analysis. Even more difficult is the undertaking of
providing already practising analysts with anything more
than just a condensed overview of the tools of the method
and the basic physical principles on which they depend.
Just as providing a lump of marble, a hammer and a chisel
does not at once result in a sculpture, so one finds that a
description of the analytical techniques falls far short of
enabling one to approach problems of analytical chemistry
in the most effective way. To achieve this difficult task, which
also involves teaching strategies, requires a more concentrated effort on the part of authors. Until that occurs we must be
content with partial solutions; even this book has failed to
achieve more than that.
With that reservation, however, I can recommend the
book especially to students and analytical chemists wishing
to make a start in atomic spectroscopy, provided that they

are not put off by its high price, which is not justifiable for
a “textbook”, despite the high standard of production and
the clear and carefully prepared contents.

Houben-Weyl. Methods of Organic Chemistry. Additional
and supplementary volumes to the 4th Edition. Vol. E 12 h.
Organotellurium Compounds. Edited by D. Klamann.

The series “Methoden der Organischen Chemie” was established in 1909 by Theodor Weyl and continued in 1913 by
Heinrich Houben. At that time, publishing a handbook in
organic chemistry in German seemed most appropriate. Today, more than eighty years later, changing the “official”
language of Houben-Weyl from German to English seems
just as well motivated. I am sure the change will increase the
international character of the series even more and I would
like to congratulate the editors on their decision.
Organotellurium compounds were previously described
by Houben-Weyl in 1955 (Vol IX), together with organosulfur and organoselenium compounds. At that time Rheinboldt used 292 pages for the description of the surprisingly
old but little explored fields of organoselenium and organotellurium chemistry. A few years ago, organosulfur chemistry was updated in two volumes of Houben-Weyl, while
the work with the organoselenium volume(s) is presently
The last twenty-five years have seen a steady increase in
the number of publications in the field of organotellurium
chemistry. Recently, a number of useful organic transformations brought about by organotellurium reactions and
reagents has focused the attention of synthetic organic
chemists on the area. Thus, organotellurium chemistry,
viewed by many as rather odd and peculiar, has now developed into an almost respectable field of research close to the
mainstream of organic chemistry.
The author, Kurt Irgolic, was very well prepared for the
gigantic work of putting together a volume of Houben-Weyl.
In 1972 he summarized all previous work in the field in “The
Organic Chemistry of Tellurium” which has since been frequently used as reference by all involved in organotellurium
research. For many years thereafter he also published annual
reports on the chemistry of organic tellurium compounds in
the Journal of Organometallic Chemistry. Unfortunately, this
work was disrupted in 1980. Since that time organotellurium
chemistry has been treated in depth only in the Patai series,
“The Chemistry of Organic Selenium and Tellurium Compounds”, Vol. 1 1986; Vol. 2 1987. Due to the organization
of the Patai series, which focuses attention on a number of
diverse aspects of the field, these volumes are complementary to, rather than overlapping with, the Houben-Weyl volume.
The contents of the present volume are logically organized
in a way similar to the one used by the author in his previous
writing. Thus, the organic tellurium compounds are classified according to the number (1 -6) of carbon-tellurium
bonds in the molecule, and their reactions subdivided according to the traditional Houben-Weyl scheme of presentation (i.e.. A. Preparation; B. Transformations). Polymeric
tellurium compounds as well as heterocyclic (3 -7-memAngen. C h m . Int. Ed. Engl. 31 11992) N o . 2
bered) organic tellurium compounds are treated in separate
sections. In addition, a chapter (150 pages) is devoted to
organic tellurium compounds without a carbon-tellurium
bond in the molecule. Compounds described in this section
include molecules where the organic moiety is separated
from tellurium by another heteroatom such as oxygen, sulfur, selenium, silicon, or phosphorus. These compounds
were traditionally not classified as organotellurium compounds but left in a no-man’s-land between inorganic and
organic chemistry.
The classification of chemical reactions as “Preparations”
or “Transformations” in the treatment of various classes of
compounds is not always consistent. For example, the reaction of a diorganyltellurium(u) species with a halogen, to
give the corresponding diorganyltellurium(iv) dihalide is
sometimes treated as a method of preparation, sometimes as
a transformation of the class of diorganyltellurium(II) compounds. The latter treatment is the preferred one. The formation of complexes of organotellurium compounds with
transition metals or electron-deficient organic molecules is
usually found under “Preparations”. However, in some
cases these compounds are also treated under “Transformations”. In my opinion the latter classification is more logical
and should be used consistently.
A third category of classification is introduced for
diorganotellurium dihalides on p. 577: “C. Diorganotellurium dihalides as synthetic intermediates”. However, when the
similar use of diorganotellurium compounds is discussed
earlier on p. 480, the material is presented as a transformation.
The present supplementary volume of Houben-Weyl contains a respectable number of references and examples from
the period (1840-1955) covered by volume 1X. The old results are often presented in the light of new findings and
contribute to a feeling of complete understanding and coverage of a certain class of compounds or reactions. In other
cases the old material was too sparsely treated in the previous version and was in need of an expansion.
The overall impression of the present volume of HoubenWeyl is that of a complete coverage of the field. The number
of papers not included can probably be counted on your
fingers. This completeness will of course make the book invaluable for all involved in organotellurium research and
those in other areas in need of information concerning
organotellurium chemistry. However, the philosophy on
which Houben-Weyl was established requires not only a
complete description of preparative methods but also their
critical evaluation. While going through the representative
examples of the present volume, I sometimes got the impression that the author should have been more selective/critical
in his choice. There are too many full-detail preparations
where the yields do not exceed 10%. For example, nobody
“skilled in the art” would ever consider trying to execute the
1 % yield synthesis of diphenyl ditelluride described on
p. 270, when there are so many better methods available.
Similarly, on p. 2 the existence of tellurium(I1) dihalides is
discussed, and it is concluded that they probably do not exist
as molecular entities in the solid state. Nevertheless, on p. 37
an example is presented where TeC1, is used as one of the
reactants for the preparation of a ferrocene derivative. Likewise, on p. 841 TeI, appears in an example describing the
synthesis of a heterocyclic tellurium compound.
An index of authors and a compound index is included at
the end of the book. The compound index is very good if you
are looking for a particular compound; however, it is of little
help if you are searching for something else. I think a book
of this size could afford also a subject index.
