for the assay of isotopic species. This book is anice contribution t o the literature of surface chemistry and heterogeneous catalysis. I t collects a wealth of mechanistic information which has been derived from relativelv classical studies of heteroee" neous catalvtic nrocesses over eneineerine, .. type surt'ares. Alrhwgh most of the results dcsrrih~dare obm~nedby rrnrtmn over surfaces which are not cleanly characterized by modern surface-spedroscopie techniques, the results described are chemical facts which have, by and large, been established by sound manipulative chemistry.

In particular, there is no discussion of microwave double resonance experiments, which provide the best illustration of propensity rules (approximate selection rules) for A J changes. The treatment of theoretical models could he improved. While i t would have significantly lengthened the hook, the inclusion of derivations would be a great help t o the novice in the field. In addition, there is very little discussion of recent accurate quantum scattering calculations on simple systems. This is certainly understandable from the point of view of an experimentalist who wants t o employ simple models rather than elaborate calculations (which are not feasible for most systems anyway) to correlate his data. Nevertheless, the reader should be made aware that computational advances now allow accurate scattering calculations with correlated ah initia potential energy surfaces for simple systems and that number of comnarisons with accurate exneriments have been made Al>o, there studlea haw shown that t h aarerment ~ hetween rxper~mentand a slmplr model often rcliulw frum n funullous cancellation of errors.

Lambert writes with some pefspeetive on the suhject of eollisional energy transfer since he has made a number of important contributions t o this field over the years, the most well known being the Lamhert-Salter plot which correlates polyatomic V-T relaxation rates with the frequency of the lowest vibration mode. The present volume is meant to acquaint advanced students and others with both theoretical and experimental aspects of energy transfer. I t is comparable in scope to Stevens' book "Collisional Activation in Gases." . nublished in 1967. and is an undated replacement for it. The author begins with a brief overview of simple theoretical concepts in elastic and inelastic scattering. No derivations are presented and familiarity with gas kinetic theory is assumed. Chapter 2 describes experimental techniques by which energy transfer has been investigated. The traditional acoustic and shock tube methods are nresented. as well as mme rrcently dcvrloped teLhniqu'es such as inrrarrd lnscr fluorwence, duublr reirmance. Raman excitation, and molwulnr k m b The last three chapters discuss vibratian-to-

and the concept of the standard state. The chapter concludes with an application of the fundamental thermodynamics t o the development of equations which will apply t o synthetic seawater samples, the composition of which are described in a reference in the text. Chapter 2 gives a mathematical review of the techniques of partial differentiation using thermodynamic expressions. A very brief survey is given to show how various computer schemes may he devised for computational purpases. The chapter concludes with a basic review of the pertinent units. The remaining four chapters deal with the topics of entropy, partial molal volumes, expansibility, and compressibility. Each chapter first presents the theoretical material dealing with the particular topic followed by applications t o the mixed electrolyte, "seawater" sample. All chapters contain an abundance of tables and figures to illustrate the various topics being presented. References in each chapter are given in terms of the author's last name and year of publication. The full citation is given a t the end of each chanter where there is a comnlete lirting dreferencei ~nalphabettmlt~rder. .4r this is the case, thrre s noauthor index at the bark uf the bouk; h#lwevrr,a ihrwical index which gives page references t o particular ions and salt5 is inrludcd.

The history of the application of interferometers t o a wide variety of infrared speetroscopie problems is very interesting. Although interferometry was developed many years ago, its widespread application to chemical infrared spectroscopic problems only came about with the advent of relatively low cost dedicated minicomputers. Once these were available, the area of interfemmetric infrared spectroscopy or Fourier Transform infrared (FTIR) expanded very rapidly. Because the entire system required the use of a computer, it was thought originally that FTIR was capable of producingfar
