Book Review Mechanisms of Inorganic Reactions. By D. Katakis and G. Gordon

been severely limited in its application to solid polymers,
because in solids, owing to dipolar coupling, one could
only obtain poorly resolved spectra with broad signals. In
the last ten years, however, techniques have been developed to overcome this deficiency and can now be used in
various ways for polymer studies. The most important
method is undoubtedly the CP-MAS procedure, in which
cross-polarization (CP), proton decoupling, and rotation
of the sample at the “magic angle” (magic angle spinning,
MAS) enhance the sensitivity and resolution of I3C-NMR
spectroscopy sufficiently to justify the description “high
resolution N M R spectroscopy of solids”.
By this technique, for example, conformational changes
can be studied. Furthermore, the anisotropic couplings
which exist in the solid state offer various possibilities for
using N M R spectroscopy to give information on the important questions of molecular ordering, e.g. alignment of
the polymer chains in stretched fibers, and phase separation in block copolymers. One can also use these effects to
study molecular dynamics, e.g. segmental mobility in crystalline and amorphous polymers, and in elastomers above
the glass transition temperature.
This book edited by R. A . Komoroski, gives an outstandingly good review of the application of the newer N M R
techniques to solid polymers. The authors of the individual
chapters are experts in polymer N M R spectroscopy. Most
of them are from the academic world, but others are from
industrial research laboratories in the United States, which
further underlines the importance of the above mentioned
developments to polymer research. Following two introductory chapters, a detailed description is given of the
study of chain conformation and mobility in rigid glassy
polymers and partly crystalline polymers using 13C-NMR
methods. After a chapter o n elastomers, the last four chapters of the book have a more physical emphasis, being concerned with local motions in the glassy state, oriented polymers, and two other important techniques, namely ‘H
multi-pulse N M R spectroscopy and ’H-NMR spectroscoPY.
The book is intended mainly for polymer chemists who
wish to obtain an overview of the capabilities of solid state
N M R techniques for polymer research. It includes enough
background information to enable one to understand the
newer N M R techniques, and most importantly it contains
a wealth of practical examples. It can therefore be highly
recommended for all laboratories engaged in the study of
the physical chemistry of polymers.

Mechanisms of Inorganic Reactions. By D. Katakis and G .
Gordon. Wiley, New York 1987, 384 pp., hand cover,
$ 53.1 5.--ISBN 0-471-84258-3
This book was written to serve as a basis for a onesemester course o n this topic for advanced undergraduate
and starting level graduate students. It was not intended as
a comprehensive review of the current literature, but does
contain a brief list of relevant books and review papers a t
the end of each chapter. In addition, appropriate problems
are given such that students can check their ability to analyse kinetic data and to asign mechanisms.
The nine chapters of the book are devoted to: introduction, mechanisms, kinetics and equilibria; events at the
molecular level-the
activated complex; experimental

methods and handling of the data; mechanism and structure; group transfer and atom-transfer reactions; electrontransfer reactions; catalysis; inorganic photochemistry. In
general the authors treat more classical type inorganic
complexes with little information on organometallic systems. In this respect the book nicely complements Jim Atwood’s “Inorganic and Organometallic Reaction Mechanisms” (Brooks/Cole 1985) which mainly concentrates on
organometallic systems.
Some sections of this book are extremely well written
and the reader will appreciate the authors’ efforts. Other
sections, for instance the introductory chapter, are rather
unsatisfactory. In general the book presents a good course
o n inorganic reaction mechanisms. Interesting systems
dealing with the reactions of dioxygen, antitumor activity
and catalysis, demonstrate the applicability of the mechanistic information. A number of shortcomings are: too
little information on the meaning of the transmission coefficient (p. 59); an organic example is used to demonstrate the effect of pressure on a rate constant (p. 67)
where so many inorganic examples are available; important fast reaction techniques such as stopped-flow
(p. 102) and T-jump (p. 104) are only treated in a few
sentences.
After having read this book. I did experience the need
for a comprehensive treatment of inorganic and organomet a l k reaction mechanisms, an update of the Basolo and
Pearson, Tobe or Wilkins treatment of the subject. With all
the activity in this field, such an undertaking will be a major task and hopefully this book will encourage an inorganic/organometallic kineticist to tackle this challenge in
the near future.

Chemical Modification of Enzymes: Active Site Studies.
Edited by J . Eyzuguirre. John Wiley, New York 1987.
187 pp., bound, E21.50.-ISBN 0-7458-0023-8
This book describes the classical methods of enzyme
chemistry, with special reference to their use for modifying
active sites; it consists of eleven chapters written by ten
authors. The papers were presented at a conference held in
Chile in 1984, and have been edited by Jaime Eyzaguirre
and published here in book form. The conference report
has thereby become a textbook-style description of known
techniques with selected examples. In relation to the present state of the techniques it is, unfortunately, already out
of date to some extent. For example, it fails to cover any of
the D N A techniques for protein modification, in particular
that of in uitro mutagenesis, and the analytical use of twodimensional N M R spectroscopy is not included. The book
thus suffers from a fault common to many conference publications, in being partly outdated by the time it has appeared.
The book can be recommended for advanced students of
biochemistry and for newcomers to the proteins field. It is
written in a comprehensible style, is well illustrated and
edited, and the individual chapters contain literature references u p to 1986. To summarize: easy reading for newcomers to protein chemistry, but containing nothing new for
specialists in this field.
