book reviews of quantum chemistry are discussed such as the many-electron atom, the HartreeFoek self-consistent-field method, electron correlation, spin-orbit interaction, molecular symmetry, the Born-Oppenheimer approximation, valence-bond and molecular orbital treatments of diatomic molecules, the SCF MO treatment of polyatomic molecules, valence-hond treatment of polyatomic molecules, semiempirical MO treatments of planar conjugated molecules and nonplanar molecules. The viral theorem and the Hellman-Feynman theorem are also presented. The topics chosen me of interest to chemists and the presentation is clear to the average chemist. Current literature references in quantum chemistry are widely quoted throughout the text. The author introduces the necessary mathematics as the physical and chemical considerations require. However, the a& tempt is not quite successful. Sometimes it interrupts the flow of thought on the physical questions and makes for a disconnected presentation of the msthematics. Some mathematics and some steps of derivations are presented in an unnecessarily detailed manner. I t may he useful for self-teaching but it may bore the student with a better mathemsticd hackground. Some important topios are presented in a terse style (e.g., comparison of the variation and perturbation methods, techniques of perturbation theory, the SCF MO treatment of polyatomic molecules, semiempirical MO treatments of nonplanar molecules, computer and quantum chemistry, the future of quantum chemistry, etc.). Despite these minor shortcomings, I still highly recommend this hook for use as an introductory quantum chemistry textbook far advanced undergraduate students and first-year graduate students with relatively poor mathematical backgrounds. I also recommend it as a reference for self-teachine. But I

This text represents a significant contribution to the new generation of quantum mechanics texts for senior m d graduate students in chemistry and chemical physics. It has a number of very attraotive features such as the extensive use of exercises and problem. These form an integral part of the development and suoceed in their purpose because the suthor has provided a remarkable 90 pages of answers, including a large section on ~olutionswith a digital computer.

Because both matrix mechanics and wave mechanics are developed from a fundamental postulate basis, the reader must possess a good grounding in linear algebra, and matrix manipulations. For those without this background a 30 page appendix on the subject is provided (taken largely from the author's 1966 hook "Mathematics for Quantum Chemistry"). After a brief semi-historicel introduction to the need for quantum mechanics (13 pages of Chapter 0) and an even briefer review of classical mechanics, the following topics are covered (pages are given in parenthesis): the postulates (16); application to particles in potential wells, rigid rotors and harmonic oseillatars (75); hydrogen atom (12); perturhation theory and variation methods (40); polyelectronic atoms (17); molecules (27); spectroscopy (23); scattering (10). Some of the treatments w e novel and interesting and many lecturers and students will undoubtedly find the text a pleasure to work through. The word "Introduction" in the title is well chosen since the hook does provide . a rigorous and well written introduction to thelanguage and techniques of quantum mechanics. Some readers may, however, consider that the author hasn't quite made it to the "Chemistry" in his title since few applications are discussed in detail (only 8 pages are devoted to polyatomic molecules). However, such criticism is somewhat unfair. This hook does not attempt to review current work on molecular structure calculations which was done so well in a similar hook by F. L. Piler ("Elementmy Quantum Chemistry," McGraw-Hill, 1968). It does not present group theory either. However, other books do cover these topics well and there is no need for them to appear under a single cover. What is important is that Anderson has written an excellent text on the more fundamental aspects of quantum chemistry.

parstus is diagrammed, and the more than a few instrumental descriptions. However, there are some inoonsisteneies and omissions. Far example, there is no mention of KBr pellet preparation in the initial ir discussion; this is found in the appendix. In thin layer chromatography, no mention is given of the visualization procedures, though this is one of the key steps in this technique. In most quslitative organic schemes, the clsssifieation of the substance by solubility is the first step. Swinehart places this in Chapter 32, though there are several chapters devoted to the subject of qualitative analysis befare thia. The most surprising omission is that no mention of nmr occurs. There are no references to the literature in the entire hook. In view of the extensive use of ir, the fact that there is no discussionof the essential steps in analysis of ir spectra is a surprise. The book has much to recommend it if the instructor is willing to make some essential additions.

A small but adequate section on the determination of physical properties, methods of separation and purification, and the theories relating to these techniques proceeds the section on the synthetic sequences. These two sections make for 8. well balanced text on the principles and practice of elementary synthetic organic chemistry, and provide sufficient examples to keep the most industrious of undergraduates busy for at least two years in the average undergraduate laboratory. The remainder of the hook wnsists of 14 pages of spectroscopic methods of identification and structure proof, 27 pages on the identification of organic compounds, snd 12 pages of tables of derivatives. It is apparent from the size of these sections that they are given only s cursory coverage.

This short book contains, ir, nmr, uv, and mass spectra for 100 compounds. In addition, three sppendices are included. The f i s t appendix gives the molecular formula, the second gives the functional group, and the third the name of the compound. If one is stuck, he is advised to look a t the &st appendix, then attack the problem with this additional information. The second appendix may be used in a similar way, and the third is the court of last appeal. The format of the problems is reminiscent of a question on an hour test or exam. There is s. description of the compound, followed by the four spectra on facing pages. This arrangement makes possible the Xeroxing of such a set of pages for exam questions. Obviously, this book can be used by anyone as a self-study guide in spectral analysis. It should be noted that there is neither discussion of the production of these

spectra nor the analysis of spectra. The student must find this information in some other source, such as Baesler and Silhersteiu, Jaekman, eto. I feel this book has a real place as a supplement to such monographs.

This book is a, smaller version of an earlier hook "Introduction to Chemistry" which included general chemistry in addition to the organic and biochemistry sections presented in this hook. As stated by the authors in the Preface, this book is intended to serve as an introduction to organic chemistry and biochemistry, and not intended for those msjoring in those fields. In t h t respect this is an exemplary textbook. This book appears admirably suited to the sophomore who plans to enter the health sciences, especially nursing. The book is divided into two parts. Part I deals with the nomenclature and the basic reactions of simple organic compounds. Since a. firm foundation in organic chemistry is essential for a. meaning-
