Optoacoustic Spectroscopy and Detection. Edited by Yolz-Hun

Optoacoustic or photoacoustic spectroscopy is one of the
most recent procedures in instrumental analysis, although
the underlying physical phenomenon was reported as long
ago as 1880 by Alexander Graham Bell. It is a variant of
classical absorption spectroscopy in the UV/visible and IR
regions, in which a microphone is used as the detector. This
combination of optics with acoustics has led to the designation
optoacoustic or photoacoustic spectroscopy. In this, the first
monograph on the new procedure nine authors, including
L. B. Kreuzer and A. Rosencwaig who are accounted pioneers
in the field, report on the physical principles, design of the
apparatus, and the possible applications, in eight independent
chapters each with its own bibliography.
An introductory chapter on signal production and detection
is followed by sections on energy transfer, the principles underlying the optoacoustic spectrometer, on tunable light sources
in the UV/visible and the IR region, and on the optoacoustic
spectroscopy of gases and solids.
The individual chapters are very clearly written and are
provided with a wealth of illustrations. The literature review
is probably the most complete that exists at present for this
field. The book can be recommended to all who are interested
in this new process of instrumental analysis and are active
in teaching and research or in the application of this area
of absorption spectroscopy.

Principles of Colloid and Surface Chemistry. By P. C. Heimenz.
Undergraduate Chemistry: A Series of Textbooks, Vol. 4.
Marcel Dekker, New York-Basel 1977. 1st edit., xi, 516
pp., bound, SFr. 64.00.
Important aspects of the extensive field of colloid chemistry
are treated in eleven chapters with the physical considerations
placed in the foreground.
After the introduction of the important experimental values,
Chapters 1-4 give an extensive treatment of viscosity,
sedimentation, and diffusion (the fundamental mathematical
derivations are given in every case), and a discussion of osmotic
phenomena. Chapter 5 discusses light scattering theoretically
and with numerous experimental examples. There follow
chapters on surface tension and adsorption from the liquid
phase, starting consistently with the Gibbs equation. The
descriptionofadsorption isothermsisplaced as thecentral point
of Chapter 8, which deals with adsorption from the gas
phase. Unfortunately, this chapter is confined to physisorption, whereas in view of the demanding title of the book
at least a brief illustration of the very important area of chemisorption could have been expected. Chapter 9 is devoted to
electrochemistry (electrode processes, Debye-Huckel and
Gouy-Chapman theory), while van der Waals interaction
and its significance for flocculation phenomena of colloidal
particles are treated in Chapter 10. The final chapter contains
information on electrophoresis and other electrokinetic phenomena.
All in all, the book covers an astonishingly wide field and
offers many details; it is forcefully and clearly written, but
also includes strict mathematical derivations wherever these
are necessary. It is designed for chemists who wish to enter
the field of colloid chemistry, though specialists too will
find the occasional useful detail.

Methodische Fortschritte irn medizinischen Laboratorium (Progress in Methods used in the Medical Laboratory). Vol.
3: Akute Syndrome (Acute Syndromes). Edited by A. Englhardt and H . Lommel. Verlag Chemie, Weinheim-New
York 1978. 1st edit., viii, 288 pp., 35 figs., 138 tables, plastic,
DM 62.00.
It is unfortunate that the subtitle “Laboratory diagnostics
of acute internal diseases” does not appear on the cover,
for what is the uninformed or even just the curious reader
to make of an “acute syndrome”? Certainly not a “group
of related acute symptoms” as given in textbooks and dictionaries.
In their foreword the editors indicate that the plan of the
book was based on the following concepts:
1. All modern methods of an emergency laboratory are to
be treated.
2. The book should be a reference work for acute situations
that call for rapid treatment.
3. Detailed references should provide a review of clinical symptoms, diagnoses, and differential diagnoses.
4. Clearly laid out tables should give side by side clinical
pictures and laboratory investigations.
The book contains the following chapters, written by a
number of individual authors: acute endogenous intoxications,
acute exogenous intoxications, acute cerebral processes : apoplexy and its differential diagnosis, acute disturbances of the
cardiovascular system, acute disturbances of hemostatis: acute
bleeding, acute disturbances in the abdominal region : the
acute abdomen, acute inflammatory organ disorders, acute
disturbances of the defense system against infections, acute
hemolytic crisis.
It must be emphasized that the clinicochemical part determines the value of the book. All essential data on methods
are described in detail or references are given to customary
test methods. In view of the progress in the field of clinical
chemistry this method of presentation will soon make necessary a supplementary volume or even a new edition.
