Scattering of X Rays by Liquids with Complex Molecules. The Choice of the Molecular Center

Abstract

The formula for the intensity of the radiation scattered by a liquid with complex molecules is discussed. It is shown that the choice of the molecular center is not arbitrary but determined by the condition that the distance between two molecular centers should have no influence upon the orientation of the molecules concerned. Also it is pointed out that Fourier inversion of the intensity formula is not always possible.
