WebFor quantitative description of a molecular charge distribution it is convenient to dissect the molecule into well-defined atomic fragments. A general and natural choice is to share the charge density at each point among the several atoms in proportion to their free-atom densities at the corresponding distances from the nuclei. This prescription yields well … WebNov 18, 2003 · The Hirshfeld and VDD charges, which prove to be numerically very similar, are to be recommended because they yield chemically meaningful charges. We stress the need to use spatial integration over an atomic domain to get rid of basis set dependency, and the need to integrate the deformation density in order to obtain a realistic picture of … ibms branchWebMay 18, 2024 · Hirshfeld constraints are cheaper to construct than Becke constraints in large systems because Hirshfeld constraints are essentially just weighted sums of spherical Gaussian functions.

Web130 F.L. Hirshfeld advanced by Politzer and Harris [4] has two compelling advantages over most of its rivals: 1) It makes the charge on each atom an unambiguous property of the molecular charge distribution, independent of the mathematical formalism used to derive this distribution; 2) When applied to the promolecule, made up of overlapping ... http://muchong.com/html/202404/5831623.html
