chemistry. Yet this lack of detailed explanations is an intentional part of the author's approach and in a book of this size much does have to be left out. The success of this monograph will probably not depend upon how the material is presented but rather how successfully it raises questions in the readers' minds, and thereby urges the readers to review and seek further information from other sources. Thus, as avery brief survey of some of the most important topics generally covered in an introductory organic chemistry course, this work can be recommended.

Physical biochemists have commonly taken a classical thermodynamic approach to investigations of multiple equilibria. As is well known, however, the nature of thermodynamics is such that one cannot predict a priori quantitative experimental results but only relate one property to another. This weakness has resulted in the less frequently employed statistical-mechanical approach outlined in this monograph. After a general introduction to the methods of statistical mechanics, the author presents a discussion of intermolecular forces, applications of statistical mechanics to the association of both m d r l nnrl natural pdypep~idrsnnd pdyrdmrt~rleqand;I rr r u 4 m is followed by a pair of chapters on cooperative phenomena, one describing the cooperative binding of various ligands to mseromolecules and surfaces and a second concerning the analysis of the intrinsic cooperative behavior of snecific moteins and nucleic acids. The

As an introduction to the application of statistical mechanics to biomedical systems (for which i t is intended), this book is quite simply excellent. Very little prior knowledge other than elementary physical chemistry is assumed, and the rather difficult material is presented clearly and concisely. It can be recommended enthusiastically to anyone seeking to understand the manner in which statistical mechanics can be employed profitably to understand complex biochemical equilibria. It should be pointed out that the title of the bwk may be somewhat misleading since the teat lacks discussions of other approaches t o the characterization of caoperative effects such as kinetic procedures and linked function analysis. Furthermore, experimental aspects and consideration of the molecular basis of cooperativity are not reviewed. Unfortunately, this hook does not include mention of a number of recent, exciting advances in the areas surveyed (the latest references, as well as the preface are dated 1974). For example, recently, Freire and Biltonen have shown that the thermodynamic parameters describing multistate macromolecular transitions can be obtained by calculation of the partition function from the calorimetrically determined excess heat capacity change of the processes (e.g., CRC Crit. Reu. Rioehern. 5, 85-124, 1978). Ross and A144 / Journal of Chemical Education

This small monograph (only 128 pp.) is a radical change from most of the currently available hooks about organic chemistry. I t is clearly not meant t o he used as a text, neither is it an exhaustive survey of the field. Rather, i t is an easily readable discussion (based on some of the author's lectures) of only a few topics central to any course in organic chemistry. This book is intended as an overview for those who have already completed a semester in an organic course or perhaps for graduate students who might want a brief refresher. The hook is divided into six brief chapters: Structure and Stereochemistry (35 pp.); Bonding (27 pp.); Thermodynamics and Kinetics (7 pp.); Substitution, Elimination and Addition (29 pp.); The Carbonyl Group (13 pp.); and Free Radical Chain Reactions (8 pp.) plus a detailed index (4 pp.). The author's aim is to emphasize only a few fundamental topics with most details omitted. An idea of the wide variety of topics covered can be gained from the fallowing sampling: constitutional isomers, cyclohexm e conformations, optical isomers, Fischer projections, atomic and molecular orbitals, E-Z nomenclature, orbital symmetry, kinetics, nucleaphilic substitutions, eliminations, carbocation stability, additions to double bonds, electrophilic aromatic substitution, reaction of carbonyl groups, free radical halogenations and bond strengths. There is also a large abundance of well-drawn figures and diagrams and the printing is essentially free of errors. A prior knowledge of organic chemistry is definitely essential to reading this book, however. I personally enjoyed reading these chapters and found the first half of the book (on structure, stereochemistry, and bonding) to be especially well done. My only criticism is the brevity of the treatments and subsequent lack of depth, especially where figures are presented with almost no discussion about them in the textual material. This deficiency could lead to confusion unless the reader has a firm foundation in the theories of oraanic

This is a welcome hook as a "trip report of the 12-member U.S. Delegation in Pure and Applied Chemistry" in their three-and-a-half week visit to the People's Republic of China in May and June 1978. This delegation should be commended for compiling a great deal of information in such a brief visit. The hook covers ten sections: (1) Roots of chemical research and development in China, (2) The institutional structure of chemical research and development in China, (3) Chemistry and Chemical engineering in the context of national science policy, (4) Chemistry and chemical engineering as elementsaf science education in China, (5)Basic research in the subdisciplines of chemistry and chemical engineering, (6) Status of research in key areas of technology, (7) Organization of chemical research and dewloo-

pendices. Particularly interesting are extensive lists of Chinese chemists, chemical enginern, and phgsiristi currently in China w i ~ hnomrs ,n Ixnh English and Chinew.'l'he liars are inr f n m cornolete Their Enrhsh names are different todey from those printed in the book, because recently the Mainland Chinese government has changed the name spelling system. But the Chinese names shown in the book give their positive identifications. In this unique and timely book much attention has been focused on the People's Republic of China since the Sino-American normalization of relations. Much of the information presented either is not available elsewhere in Western countries, or can be obtained only by tedious sifting through the literature. In the three-and-a-half week trip, the delegation traveled to ten cities, usually

book reviews open to foreign visitors-Peking, Talien, Shenyang, Changehun, Harbin, Tach'ing, Shanghai, Hangchow, Sian, and Lanchow. Two eminent Chinese Americans, fluent in Chinese, were exceedingly helpful members of our delegation. Their itinerary was very tightly arranged and allowed only a one or two day stay in each city. This program is comparable to a three-week guided tour of ten countries in Europe. The delegation did not go to Szechuan and Anhui, but some information about these two orovinces was included in the book. It is assumed that ----some information in the book was provided by the Chinese government. There was much the delegation did not see and they undoubtedly were not shown.

Although this hook contains very little political flavor, the Cultural Revolution and the damaging effect of "Gang of Four" an science and Chinese scientists were unavoidably mentioned. The authors stated that the Chinese science system is variegated and complex beyond their complete understanding. They concluded that the major question for the future is whether the Chinese will be able to absorb and capitalize on high technology. The principal uncertainties are the chance far political stability, and the survival of a political leadership which is pro-science and pro-technology. Hua Kuo Feng, Teng Hsiao Ping, and Fang Yi (Vice President of the Chinese Academy of Sciences) addressed the National Science Conference held in March 1978. In Fang's "Draft Outline National Plan for the Development of Science and Technology, 197885," China wants to narrow "...thegap (with the advanced countries) ta,about ten years" and to lay "... a solid foundation for catching up withor surpassing advanced world levels in all branches in the following 15 years." Hua's 1978 ambitious 10-year economic development plan calls for strenous efforbto be made to double or even triple grain produetion within the next 8 years. This hook reported in some detail ahout Chinese National Science Policy including 8 priorities: agriculture, energy, materials, computer science and technology, lasers, space, high energy physies, and genetic engineering. These plans have been skeptically received by outsiders as political slogans in viewing lack of funding (short of hard currency) and scientific manpowen (most of the leading scientists whoare 55-70 years of age are Western-trained). Despite these shortcomings, a national political commitment to rapid scientific and technological development has been made since 1977. Given the essential elements of political stability, good leadership, adequate funding and resources, anda functioning intrastructure of research and educational institutions, the results could he dramatic. There is a minor oversight, in the translation of one of the slogans in the cover. It should read, "In itidustry, learn from Tach~

'ing" instead of "Learn from Tach'ing". There is a sister slogan commonly seen in China that reads, "In agriculture, learn from Tasai." Tasai is located in Shansi province which was not included in their trip. I enthusiastically recommend this highly readable book t o those who are interested in the recent scientific developments in China and the goals set forth by the current Chinese leadership for the next 10 to 20 years. This bcak represents an important step toward the understanding and transfer of chemical information between two countries. K . L. Cheng Universny of MisouriMansas Cify Kansas City, MO 64 110

Alkall Halide Vapors: Structure, Spectra and Reaction Dynamics Editors: P.Dauidouits and D. L. McFadden, Academic Press, New York, 1979. v + 542 pp. Figs. & table. 23.3 X 16 cm. $55.00. The twenty common alkali halides (from LiF to CsI) form an intriguing and eatensively studied class of molecules. In the simple ionic model, their ground states near the potential minima arise from the interaction

of two closed-shell ions. At large internuclear separations a covalent description becomes appropriate as the molecules dissociate toward atoms. The "crossing" of ionic and covalent potential curves dominates the dynamics of simple chemical reactions involving the alkali halides. These reactions have been studied extensively in molecular beams, principally because alkali atoms and alkali halide molecules can be detected in very low concentrations by surface ionization deteetors. Nearly all the early beam experiments on reactive collisions used this method of detection, and the period 1955-65 is sometimes referred t o a s the "alkali age." The introduction of alternative detectors has destroyed this monopoly, but the interest in alkali halide collisions remains strong. The volume under review consists of fifteen articles, by a distinguished group of contributors, on the properties and reactions of alkali halide vaoan. Ten of the articles deal with molecular collisions, mostly in beams, while the remainder discuss thermadynamics, spectra, and theoretical models. Collisions involving both ground and excited states are covered, and numerous examples of both "direct" and "collision complex" reaction mechanisms are presented. These anicles form much more of a coherent whole than is usual for compilations of this sort. A large amount of quantitative data is displayed in tables, to which editors have prepared an index, in addition to a four-page general subject index. These, along with a detailed Table of Contents, will help to make this book useful as a secondary reference source as well as an introduction to the literature. (Continued on Daze A1461
