In Bader's theory of Atoms in Molecules, we partition a molecule into "atoms" which are separated from each other by surfaces of minimum charge density: You can then calculate the partial charges of the "atoms" in the molecule, e.g. H 2 O might yield: A t o m C h a r g e O − 1.150 H + 0.425 H + 0.425.

Webb18 nov. 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 …
WebbA new viewpoint on iterative Hirshfeld charges is presented, whereby the atomic populations obtained from such a scheme are interpreted as such populations which reproduce themselves. This viewpoint yields a self-consistent requirement for the Hirshfeld-I populations rather than being understood as the result of an iterative … WebbThe Hirshfeld population analysis scheme which carves the molecular density into atomic density contributions is tested. This method does not require a reference to basis sets or their respective locations, but is based on a different physical and mathematical footing.
