Polymers. Properties and Applications. Vol. 7: Introduction
to Polymer Spectroscopy. By W. Klopffer. Springer-Verlag, Berlin 1984. xii, 184 pp., bound, D M 98.00.--ISBN
3-540- 12850-6
This book is a valuable addition to polymer literature.
The range and organization make it possible to grasp the
aim of the author very rapidly. This book is intended as a
cohesive synopsis of the most important physical and
chemical aspects of polymer spectroscopy written in the
style of a second-semester lecture. An up-to-date presentation of the various modern methods is aimed at. In this
sense this book is a review of and introduction to the spectroscopic methods of polymer physics and chemistry,
which can be recommended to the first degree student and
to the “research novice”. The literature reviewed at the end
of each chapter enables the interested reader to deepen his
knowledge.
Electronic, vibrational and magnetic conditions are
dealt with at a similar level and supplement the numerous
books on polymer spectroscopy. This is revealed by the
main chapters entitled “Electronic Spectroscopy”, “Vibrational Spectroscopy” and “Spin- Resonance Spectroscopy”
which are of almost equal length. The work is rounded off
with an introduction to the definition of polymer spectroscopy, to the information contained in the spectra and the
field of spectra and with rather too short a conclusion. As
is to be expected from the subtitle, this book only skims
the surface all the way through. The various topics in the
three main chapters are only dealt with very fleetingly. On
the one hand, this has the advantage that the reader can
very quickly review the many spectroscopic possibilities.
On the other hand, it is not possible for him to enhance his
knowledge; there is no room even for explanations, which
are of such great importance to the student. A deeper understanding is only possible with a lecture or by studying
the literature which is cited.
There is no theoretical explanation of the material presented. The quantitative description is kept very basic and
too short. Although the book is intended for teaching most
of the formulae are assumed to be known and are described in too cursory a manner as are the figures.
Unfortunately this book has its weak points. The following may be quoted as examples:
-P. 73, Fig. 6.9 has three arrows but four laser lines with
the wavelengths given in nanometers which the reader
has to recalculate for himself in wave numbers along the
axes, in order to obtain an assignment. The direction of
the polymer axis is incorrectly marked.
-P. 79 “Using polychromatic radiation .. . the resulting interferograrn has the form of a damped oscillation.” A
damped oscillation is obtained with a Lorentz line.
-P. 116 “The relaxation processes deactivating the energetically higher (“excited”) state . .. are T, (spin-lattice
relaxation) and T, (spin-spin relaxation)” and later on p.
159 “. . . roughly analogous to luminescence decay.” T ,
and T2 are coherence-destroying processes whereby only
T, is to be correlated with decay of the excitation and
not Tz which describes the loss of phase.
-P. 120 (ESR Experimental) “The sample has to be introduced into the region of highest magnetic field
strength.” This does not refer to the static magnetic field
but to the magnetic field component of the oscillating
microwave field. Further: “The frequency can be preAngen.. Client. I n r . Ed. Enyl. 24 IIYN.7) No. R
cisely kept constant by modifying the tension of the reflector (AFC)”. “Tension” is an error in translation,
what is meant is voltage or potential. The abbreviation
in brackets AFC = automatic frequency control is not explained. This circuit is not intended to keep the frequency constant but to drive the frequency of the clystrons in frequency variations especially in resonance
transition.
-P. 132, Fig. 9.15. Instead of 2E only E appears in the energy level scheme, axis I1 B should be B 11 y, the Zeeman
splitting has an incorrect starting point. Too much importance should certainly not be attached to this list
compared with the merits enumerated and the overall
good impression made by this book. However the student will surely ask himself whether or not he ought perhaps to expect more of an English language book costing almost 100 DM, even if only from the point of view
of scope. At this price it is not to be expected that the
book will be widely sold.

Hemoglobin: Structure, Function, Evolution and Pathology.
By R . E. Dickerson and I . Geis. Benjamin/Cummings
Publishing Co., Menlo Park, CA 1983. 176 pp., bound, $
40.50.- ISBN 0-8053-241 1-9
The authors are known internationally amongst other
achievements for their excellent book “Structure and
Function of Proteins” published in 1969. Their new book
is based on this in that the first chapter “The Rules of the
Game” has only been changed slightly. The second chapter “Hemoglobin Structure and Function” contains sections of the previous book but also presents many details
of new research results. The third chapter “Evolution of
Oxygen Carriers” which reflects the authors’ interests in
general questions of natural history is a pleasure to read.
The last chapter deals with “Abnormal Human Hemoglobins” and elegantly bridges the gaps between medicine,
molecular biology and physical methods of structural analysis. The title “Hemoglobin” is too narrow judging by the
contents of the book; this is particularly evident in chapters I and 11.
The outstanding indefatigable life work of Max Perutz
as well as the efforts of other scientists have led to a
wealth of information on hemoglobins. As important biological and chemical concepts of protein research are
based on a mosaic of experimental details, the authors of a
monograph face a difficult problem. Either older results
can be presented as simple and approved concepts, or new
data can be offered, fresh and hence scarcely filtered. Dickerson and Geis have decided on the second alternative.
Readers who are unable to review the literature on hemoglobin strewn throughout the world will find a lucid, comprehensive and exact presentation together with the original references.
In conclusion, this book is to be most warmly recommended to all scientists and physicians who are interested
in the relationship between structure and function of macromolecules. Throughout the book there are general principles exemplified by hemoglobin which will fascinate
