After publication of 11 volumes since its beginning in 1965, this series has adopted several "area editorships" with this volume. Topics reviewed in seven chapters include: the use of high-pressure liquid chromatography in pharmacology and toxicology; chromatographic separation and molecular-weight distributions of cellulose and its derivatives; practical methods of high-speed liquid chromatography; measurement of diffusion coefficients by gas-chromatography broadening techniques; gas-chromatography analysis of polychlorinated biphenyls and other nonpesticide organic pollutants; high-performance electrometer systems for gas chromatography; and steam carrier gas-solid chromatography· * Vibrational Spectra and Structure, Vol. 3.

This latest volume of the series presents critical summaries of recent work as well as suggestions for fruitful areas of future work in the field of vibrational spectra. Chapter 1 describes detailed application of symmetry group operations to both rigid and nonrigid molecules. Chapter 2 covers

Reviewed by Milos Novotny, Department of Chemistry, Indiana University, Bloomington, Ind. 47401 "Basic Gas Chromatography" is one of the series of ACS Audio Courses which provides for a practical introduction to a rather broad field. The fundamentals of gas chromatography are explained through taped lectures replayed on a cassette player by a user and supplemented by a manual of 110 pages. This course consists of six basic chapters on the fundamentals, instrumental aspects, and the analytical techniques of gas chromatography (total playing time of 4 hr). Numerous references to both basic and specialized books and commercial literature are also included. The basic and practical aspects of gas chromatography are presented here in a clear manner, and the discussion of most subjects is adequately developed. Practical information on laboratory techniques presented by the author can also be valuable to a user of gas chromatography. Those who could potentially benefit most from "Basic Gas Chromatography" are laboratory technicians and workers in nonchemical disciplines using the method. The course would be less valuable to a college chemistry student. Most of the chapters are well balanced. The part dealing with quantitative techniques appears as best. Least satisfactory and rather sketchy is the introductory part. In spite of the practical orientation of this course, it is felt that a more adequate discussion of the physical principles of chromatography and the mechanism of zone broadening should be presented. Furthermore, even in certain very practical directions, the text is not particularly up-to-date (e.g., in the areas of general instrumentation, column technology, and sampling systems). For instance, more recent and pertinent references to work on gas chromatographic detectors and ancillary techniques would be desirable.

Although there exist several good and more comprehensive books on gas chromatography, this practical approach to teaching the fundamentals deserves attention. With rapid expansion of gas chromatography into both research and routine laboratories in and outside of the field of chemistry and concern about its adequate teaching and popularization, this instructional approach could be successful. Just as with many other subjects, the instruction through tapes may become increasingly popular. Inaccuracies in the text and typographical errors in the manual are relatively minor.

Reviewed by Ramon M. Barnes, Department of Chemistry, University of Massachusetts, Amherst, Mass. 01002 This material is the third in a series of tape-recorded symposia presented by the American Society for Testing and Materials at the Pittsburgh Conference on Analytical Chemistry and Applied Spectroscopy. The audio tapes accompanied by a booklet of figures and tables keyed to each presentation make conveniently available current information for those who cannot attend the original symposium. The two tapes include five talks which describe the determination and correction of spectrochemical analytical curves based upon computer methods in optical emission spectrometry and X-ray fluorescence spectroscopy. Algorithms and procedures are discussed for curve fitting and scaling, as well as corrections for spectral line interferences, instrument drift, interelement matrix effects, and distribution of standard concentration values. In the first presentation, J. Kelly describes examples of functional relationships affecting analytical curves for optical emission and X-ray fluorescence spectroscopy. The algorithms for each of eight major effects are given. Four types of spectrochemical reference materials for establishing instrument drift, spectral line coincidence, matrix effect, and certified calibration are also described. Determination of polynomial coefficients in curve fitting programs for photographic emulsion equations and analytical curves is discussed by J. Hur-

witz in the second talk. The difficulties encountered and programmed safeguards required for the application of high-order polynomials are demonstrated. The capabilities of a high-level executive software for a commercial emission spectrometer applied in calibration, standardization, and analysis are illustrated by J. Carroll in the third talk. The preparation of analytical curves and corrections for X-ray fluorescence methods are described by D. Sermin and K. Krapp and then illustrated in the final presentation by D. Moyer in the determination of trace elements by X-ray fluorescence spectrometry. Questions and discussion for each presentation are wisely assembled at the end of the symposium to maximize the continuity of the recordings. The tape reproduction quality is good; the illustrations and tables are easily read, and the presentations readily followed. In one way the recordings are superior to the original talks in that a listener may replay any portion or study the figures at length. As an introduction or a review, this symposium is useful. Unfortunately, brief conference presentations are generally superficial, especially when they consider sophisticated computer programs. These presentations are long enough to provide a sampling of the problems and capabilities, but the detailed descriptions required for actual implementation are lacking. Consequently, an interested spectrochemist might ask whether the $15.25 purchase price might be better spent on a good textbook or journal subscription rather than on these tape recordings. Overall, these tapes are a useful and modern commentary on the status of computer operation of spectrochemical readout systems.
