book reviews Safety precautions appear to be ade-

quate throughout the manual with the possible exception of the Victor Meyer ex- periment which calls for mercury as a cushioning fluid in the vaporizing chamber. (The vapor pressure of mercury at 1 0 0 T is ahout 100 times its value a t room tem- perature.)

The book has no large section dealing with a.pparstus and methods in general. A five-page introduction deals with such general topics as objectives, safety, clean- liness, report writing, and errors. Brief discussions of thermostats and the purifica- tion of mercury are given in the appendix.

Phyricol Chemistry: An Advonccd Treatise. Volume 3, Electronic Structure of Atoms and Molecules

Edited by Douglas Henderson, IBM Re- search Lnborat,ories, San Jose, California Academic Pl.ess, Inc., New York, 1968. xv + 612 pp. Figs. rtnd tables. 15.5 X 23.5 cm $22.50.

When approaching any volume or volumes laheled as a Treatise, one often is uncertain what to expect inside the covers. The editors of "Physical Chemistry: An Advanced Treatise" have clearly stated their int,ention far the eleven volumes projected far the series. "The purpose of this treatise is t,o present a comprehensive treatment of physical chemistry for ad- vanced studentil and investigators in a reasonably small number of volumes. We have attempted to include all important topics in physical chemistry together with horderline subjects which are of particular interest and importance. The treatment is a t an advanced level. However, elementary theory and facts have not been excluded but are presented in a concise form wit,h emphasis on laws which have general importance. No attempt has been made to be encyclopedic. However, t,he reader shoold be able to find helpful references to uncommon facts or theories in the index and bibliographies."

Vohtme 111, dealing with the electronic strnetore of atoms and molecules, fits well within the limitations the editors have specified. Each of the articles dealing with this subject is handled expertly and eonciiiely. For persons already familiar wit,h topics that are discussed here much of the material provides a relatively compact and generalized review of the theory. Phyieal chemistsspeeiali,liaing inotherareas should find these srtieles a suitable entre into the field if they are willing to sacrifice some of the introspective discussion that is often of pedagogical value but generally missing here. This conciseness may in- ereme the level of difficult,y somewhat,, but at, the same time the scope of topics is broad and most of the modern schools of t,haught in quantum theory are repre- sent,eri. . .-

The chapter headings involume I11 are Bitsic Principles rtnd Methods of Quantum

Mechanics (D. ter Haar), Atomic Struc- ture (S. G. Davison), Valence Bond and Molecular Orbital Methods (E. R. David- son), Electron Correlation in Atoms and Molecules (R. Paunce), Atomic Spectra (W. R. Hindmersh), Eleotronic Spectra of Diatomic Molecules (R. W. Nicholls), Electronic Spectre. of Palyatomic Mole- cules (L. Goodman and J . M. Hallas), Pi Electron Theory of the Spectra of Con- jugated Molecules (G. G. Hall and A. T . Amos), Ionisat,ion Potentials and Elsctron Affinities (C . A. McDowell), and Elactron Donor-Acceptor Complexes and Charge Transfer Spectra. (R. S. Mulliken and W. B. Person).

While one may miss the lucid exposition of s single author, i t is entirely appropriate that topics i t this advanced a. level be treated by persons well-versed in each specialty. Despite multiple authorship, the nomenclature and the tone remain rea- sonably consistent throughout. Each author seems to have done a commendable jab of presenting not only the basic theory and experimental background appropriate to his topic hut also the scope of current re- search and theoretical approaches without indulging too extensively in personal idiosyncrecies. There are included a. num- ber of helpful compilittions of data from both experiment and theory for compari- son. The projected volume V of the Trea: tise is scheduled to discuss Valency. Presumably here will be found discussions of more empirical and exploiatory ap- proaches to the structure problem.

I n summary, "Electronic Structure of Atoms and Moelcules" is a tightly-written and well-handled series of articles suitable for physical chemists a t a. somewhat ad- vanced level. I t will not he the place for the undergraduate student or the typical synthetic chemist to turn for inspiration, but i t serves its intended purpose very well and should find extensive use by physical chemists seriously involved in problems related to these topics.

Chromatography

Edited by D. R.Browning, Bristol Poly- technic, England. McGrzw-Hill Pub- lishing Ca., Ltd., London, 1969. (May be obtained fmm New York office.) vii + 161 pp. Figs. and t~b les . 14 X 21.5 em. Softbound. 328.

This book sets out to present chrama- tography in asimplefashion and at aninex- ~ens ive rice. The editor, in the preface. hopes th&t this text (along k i th twb others in this series on instrumental methods) will "provide the chemist with an authori- tative and accurate account of the sub- ject." There is certainly a. need for such s book, especially as a supplementary text in an instrumental analysis course, and the editor's eoals are indeed laudable. Never- theless, this reviewer feels that the hook has little to recommend it, and indeed, it is felt to be unacceptable.

Misleading statements and omissions abound throughout the book. In the

most important omission, no mention is made of the large amount of work that has beeu performed in separation of proteins by gel chroma.togrefihy (Chapter 8). In- deed, Porath and Flodin's work is not even referenced rtt the end of the chapter. Even in Chapter 1, p. 1, there is a mis- leadine statement. The author states

tography, analyses down to the picomole range have been performed. On p. 7 it is stated that the isotherm ir rarely linear in adsorption chromatography. This stste- ment is completely misleading for it ne- glects the excellent work performed by Snyder and others in adsorption chroma- tography. With control of water content on the adsorbent and reasonable sample sizes, good linear conditions can be achieved. I n one final example, on pp. 90 and 91, i t is implied that capillary columns in gas chromatography have greater sepa- ration potential than packed columns be- cause of the large number of theoretical plates. Indeed the famous 1 million theoretical plate oolumn is noted. What the author fails to point ont is that the void volume in these columns is so Large, relative to packed columns, that the capac- ity ratios are significantly smdler. As a result, resolution is not too different in packed and capillary columns.

The book has a number of typographical errors. For example, on p. 103, this re- viewer found three names in 11 references spelled wrong. Cross-referencing within the text also leaves much to he desired. Of much more importance is the poor edit- ing job. I t seems as though each chapter has heen written completely independent of all others. For example, Rr values, as well as displacement, elution, and frontal analysis are described in a t least 3 different places. Further, Chapter 2 begins with a reference to the theoretical treatment in Chapter 1. This reviewer found little if any theory in Chapter 1, only a. rather in- complete introduction into chromatog- raphy. Finally, the concept of polarity is discussed in Chapters 1 and 2 (with only 8 pp. separation). Surely an editor could have caught many of theseproblems.

The references to further reading a t the end of each chapter were either poor or in- complete. Far example, Samuelsan's book on ion-exchange has a more recent edition than 1963. I n the gas chromatog- raphy chapter, no reference is given to Dal Nogare and Juvet's nor Purnell's hooks. Instead, we me recommended to look at international symposia books. I t is thus implied that a. student finishing the gas chromatography chapter could delve right into advanced literature. I sincerely doubt this. The supreme surprise was the reference to the Journal of Chrmalography a t the end of Chapter 1 for further reading With many thousands of pages over the years, where should the student begin? Thereis no guidance from the author.

Finally, and perhaps the major prob- lem, is the almost complete lack of princi- ples of chromatography in this book. Nowhere is there the least discussion of resolution.
