Applications of Fourier-transform theory to electron-density extraction of Patterson functions
Published/Copyright:
July 28, 2010
Abstract
Fourier-transform theory applied to Patterson syntheses in which the coefficients are modulated by a known or assumed partial structure lead to criteria, based upon peak heights and upon geometrical positions, which allow electron-density extraction procedures in which incorrectly placed atoms can be identified. Modified Fourier syntheses are presented also for relative enhancement of the correct structure over the background, and for location of the third coordinates of atoms for which two coordinates are already known.
