Notes:
Standard density basis functions for hydrogen and the first-row atoms have been converted to K-shell and L- shell scattering factors. With the K shell fixed at two electrons, these scattering factors have been used for atomic-charge analysis of X-ray structure factors by the method of least squares. Results for cyanuric acid and uracil are given. The net charges for these cyclic amides are in reasonable agreement. It is recommended that scattering factors here be used for atomic-charge analysis of first-row atoms in routine structure refinements of chemically related molecular crystals.
