the similarity principle has been applied in both infrared and
ultraviolet spectroscopic data correlations with solvent and
substituent effects. The principle is revealed as a powerful
tool in the organization and analysis of a very large body of
data. In Chapter 6 (Langhals) the rather vexing issue of solvent effects is addressed within the context of binary solvent
systems. This chapter contains a number of useful tables of
relevant parameters. Chapters 7 (Oszczapowicz), 8 (Jaworski and Kalinowski), and 9 (Zalewski) support the notion that similarity modeling is usually the most appropriate
means of establishing structure-property relationships in the
respective fields of gas chromatography, organic electrochemistry, and food chemistry. The former two make use of
linear free-energy relationships whereas the latter applies a
principal component analysis and also discusses the mathematical foundations of this type of approach. Chapter 10
(Livingstone) offers a general overview of quantitative structure-activity relationships and is one of the most readable
chapters in the book. Not only does it serve as a valuable
introduction to neophytes, but it also reports on a number of
significant advances made since the late 1970s. This chapter
includes a total of 513 references and an appendix listing
software suppliers. The final Chapter 11 (Charton) treats the
author’s own approach to the quantitative description of
steric effects. This chapter is also well-written and informative, containing among other things, several tables of atomic
radii and two appendixes on the parameters used in regression equations. The index to the volume is adequate, though
I would have preferred to have found more multiple entries
in it.
As a whole this work is not comprehensive in its coverage;
nor it is really suitable for use as an introductory text on the
various applications of similarity modeling. Its appeal will be
rather to those researchers and others currently engaged in
the more conventional approaches to structure-activity relationships in chemistry.

This book on photochemistry (originally published as
Technologie Photochimique, Presses Polytechniques Romandes, Lausanne, 1986) is the first to be concerned primarily with the technical aspects of such processes, especially in
connection with organic photoconversions that have been
and are being utilized in economically viable industrial processes. I have not previously encountered a book that gives
so much valuable information on experimental procedures
and apparatus used in both laboratory scale and pilot plant
photochemical reactions. The first chapter is concerned with
photochemical principles (e.g., absorption spectroscopy,
photophysical decay processes of excited states, energy
transfer, etc.). While entirely sufficient for the purpose of this
book, this chapter is (appropriately) not as comprehensive as
treatments in other well-known photochemistry texts. The
chapter on radiometry and actinometry provides more detail
on these subjects than I have previously seen in any book,
supported by relevant theory, and many figures and tables.
The next two chapters, concerned with light sources and
filters and photochemical reactors, totaling almost one hun360

dred pages, are remarkable. The information here is of enormous use to anyone planning to carry out photochemical
reactions on any scale. Detailed schematic figures of lamps
and reactors in ordinary and not so ordinary use are provided, along with extensive tables listing characteristics of various types of lamps, lasers, and filters. The extremely detailed
figures, which cannot be found elsewhere, clearly required
enormous care and effort to produce.
The rest of the book provides a wealth of information
about a number of photochemical conversions that have
found diverse industrial applications. Technological details
regarding all stages of these processes are given, with abundant references to the patent literature. Again, this kind of
information is not available in any other source, and must
have taken great effort to compile. Specifically, these chapters cover photonitrosylation, photochlorination, photobromination, sulfochlorination and sulfoxidation, photochemical desulfonation and desulfonylation, photohydrodimerization, photooxidation, and vitamins. While the
mechanistic aspects of these reactions are not the main focus,
a significant amount of such discussion is included in each
case. The economic aspects of these processes are discussed,
along with safety considerations. The wealth of useful information is staggering. The authors have clearly shown, for the
first time in my experience, the potential as well as the limitations of photochemistry on an industrial scale, and they
put the lie to the common criticism that photochemistry is an
arcane subject with no significant practical applications. The
one important subject that the authors do not treat with the
attention it deserves is solar energy conversion, which I hope
they will address in a future book or future editions of this
In summary, “Photochemical Technology” is a wonderfully useful book which admirably fills an important gap in
this field. It is highly recommended to anyone involved in the
practice of photochemistry, from students to researchers to
engineers. It is an indispensable compendium of easily accessible information, presented in a clear and lucid style that
readers at all levels will appreciate. No one involved with
photochemistry should fail to include this book in their personal as well as institutional libraries. The authors are to be
congratulated for their remarkable achievement.

This book is divided into two parts: the first has 13 chapters devoted to theory and general practices of TLC, while
the second has 18 chapters dealing with applications based
on compound types such as amino acids, peptides, antibiotics, carbohydrates, lipids, natural pigments, inorganics
and organometallics, pesticides, pharmaceuticals, steroids,
synthetic dyes, and vitamins. There are also chapters on
