Abstract

Fouriersynthese von Kristallen und ihrer Anwendung in der Chemie by W. Nowacki 224 Book Reviews Works intended for notice in this column should be sent direct to the Editor (P. P. Ewald, Polytechnic Institute of Brooklyn, 99 Livingston Street, Brooklyn 2, N.Y., U.S.A.). As far as practicable boobs will be reviewed in a country different from that of publication. Fouriersynthese yon Kristallen und i h re An- wendung in der Chemie. By W. NOWACKI. Pp. 237, with 120 figs. and 28 tables. Basel: Birk- h~user. 1952. Price 34.30 Swiss francs. This book, a new member of the series 'Lehrbiicher und Monographien aus dem Gebiete der exacten Wissen- schaften', developed out of a course of lectures given by the author at the University at Bern, Switzerland. Al- though the book was published in 1952, it was substan- tially completed in 1948. It is only the second book to appear on the specifically restricted subject of crystallo- graphic Fourier synthesis; the first, that of A. D. Booth (Fourier Technique in X-ray Organic Structure Analysis), is comparatively brief and less detailed. The present book was intended for use both as a textbook for students and as a general work and reference book for those engaged in crystallographic research. Approximately the first half of the book is devoted to Fourier synthesis of electron density. I t deals first with the elementary theory of Fourier synthesis and with the development of equations in forms useful for practical work, then with subjects pertinent to the interpretation of electron-density functions (errors, termination-of-series effects, refinement methods), and finally with the problem of determining signs and phases (trial-and-error, iso- morpheus replacement, heavy-atom technique, Banerjee- Hughes method, Harker-Kasper inequalities). Most of the remainder of the book deals with Patterson synthesis and the related topics of Harker synthesis and Buerger implication theory. The final section of the book deals
