Internationale Tabellen zur Bestimmung von Kristallstrukturen

Abstract

THE subject of X-ray analysis is difficult because it demands a knowledge of many widely different branches of science. The central problem, that of determining the relative positions of the atoms in the crystal, which in most cases includes the molecule, is obviously of supreme interest to chemistry. A new metrical chemistry is, in fact, rapidly being built up, based upon accurate measurements of interatomic distance and valency angle, which must in the future form an important connecting link between accumulated empirical data and theoretical developments. But although the subject matter is largely chemical, the investigator requires a specialised knowledge of other, and rather diverse, matters. The more abstract portions of crystallography and group theory are necessary in deriving the results, while on the practical side a knowledge of the physics of X-rays and diffraction experiments in general is desirable. It is also customary nowadays to make fairly extensive use of analysis by Fourier series in computing the more refined results, and considerable use of atomic theory is necessary in calculating the /-curves of different atoms.
