This boak is one of several recent tenthooks to appear in the field of applied chemical kinetics and reactor engineering. Both authors have had many years of experience and are highly respected research workers in this field. Thus, one expects the book t o be authoritative, and it is. There is a broad range of material covered-probably broader than any other competing text-with many realistic examples and homework problems. In addition, there are many valuable literature references far further reading. Although one never knows a textbook well until he or she uses it in classroom teaching, this reviewer's impressions are that the book would he difficult t o use as an introductory undergraduate text. Difficult conceptual ideas are resented a little too efficiently,and they are illustrated with rather complicated industrial examples which do not emphasize the points under discussion. (These same features make the book more interesting for the initiated, however). In addition, the layout does not serve to underline the key conrents an which the student should con-
coverage and wealth of practical examples will introduce the student to subtle details and interesting specjal reactor designs encountered in practice. In summary, this book is avaluable r e f w ence for the practicing kineticist and reaction engineer, and it would appear to he apromising textbook for advanced courses in chemical kinetics and reaction engineering.

This book is the second edition of "Carbon-13 Nuclear Magnetic Resonance for Organic Chemists." The slight change in title is appropriate because 13C NMR has now become an indispensable tool for bio-, physical, inorganic, and organometallie as well as organic chemists. In its second edition, this book remains a general, low level introduction t o the theory, experimental aspects, and applications of '3C NMR.

The title, "Computer Calculations for Multicomponent Vapor-Liquid and LiquidLiquid Equilibria" is very similar to that of the 1961 edition, "Computer Calculations for of 1980.
