near to far infrared. Most of his charts extend out to 200 μ and greater. The methods he shows for the calculation of optical constants are complete enough to make this book a standard for deciding on the particular method one might select to use in work of this nature. Because this book describes the the­ oretical aspects of infrared instrumen­ tation and measurement, it obviously should find a place in the library of those who are concerned with design of infrared instrumentation and measure­ ment of infrared energies. Its com­ pleteness in this area of infrared spec­ troscopy makes it a valuable reference book. However, its usefulness is most certainly directed to the physicist and physical chemist who are more con­ cerned with instrumentation than with applications.

Reviewed by James V. Quagliano, The Florida State University, Talla­ hassee, Fla. 32306. This book is an exhaustive collection and a sound critical appraisal of the metal-ligand vibrations reported through 1964, with some important references from 1965 and 1966 as well. The book is ideal for the experimental­ ist who is concerned with metal-ligand vibrations as a diagnostic tool in struc­ tural and bonding studies; many other chemists will find this book invaluable as well. There are seven chapters in the book; one chapter each is devoted to metal-hydrogen, metal-halogen, metaloxygen and metal-nitrogen frequencies. Two chapters deal with metal-carbon vibrations; of these chapters, one is devoted to carbonyls and cyanides, the other to alkyl, aryl, and π bonded com­ plexes. The last chapter is actually an interim report on the state of knowl­ edge of the metal-ligand vibrations of the heavier group VB and VIB ele­ ments, and also includes some data on metal-metal vibrational frequencies through the autumn of 1965. The major features of the book are the large amount of clearly tabulated

data (which comprise over one half of the book), and literature references (over 1100), most of which are readily available. In addition to the large amount of tabulated data, there are in­ cluded many molecular diagrams, sum­ mation charts, a few important spectra, and an appendix containing character, correlation, and site symmetry tables. Both Raman and infrared spectra of metal-ligand vibrations, as well as the important ligand vibrations, are dis­ cussed. When there are disagreements in the literature on band assignments, a full discussion of the different assign­ ments is given. The book is well written and clearly organized—each chapter first examin­ ing the simplest, most symmetric spe­ cies for which unexceptionable assign­ ments have been made. These then serve as a basis for the discussion of the more complicated molecules and spectra. The effects of symmetry, sol­ vents, lattice modes, and coupling be­ tween vibrational modes of the same symmetry are discussed and illustrated. Such an exhaustive and clear collec­ tion of data as that presented in this book allows the reader to recognize that there are still many areas of this field to be explored. For example, appar­ ently no M-N stretching frequency for Ag(NH : l ) 2 + has yet been identified. This book was first published in Great Britain in 1967, and then in the United States in 1968—without any ap­ parent updating of the material in­ cluded. However, the author intends to update the book from time to time, which should be appreciated by all who work in this area. This exhaustive compilation and critical evaluation of spectral data, which may be updated, but never outdated, will be of value to most chemists. Treatise on Analytical Chemistry, Part 3 : Analytical Chemistry in Industry, Vol. 1. / . M. Kolthoff, Philip J. Elving, Fred H. Stross, Edi­ tors, xxiv + Jf.57 pages. John Wiley and Sons, Inc., 605 Third Ave., New York, Ν. Υ. 10016. 1967. $17.60. Reviewed hy C. M. Marstiller, Alu­ minum Co. of America, Alcoa Re­ search Laboratories, P. O. Box 772, New Kensington, Pa. The third of a three-part, compre­ hensive account of analytical chemis­ try; this book is a daring and reasonabl)- successful attempt to present ex­ perience in graphic form. This part of the Treatise deals with operational re­ quirements of analytical chemistry as practiced in industry rather than with analytical techniques. In a note about Part I I I , the editors state—"we still felt that our Treatise would be com-
