Generate input files for isolated atom computations using one of the following programs: Gaussian03/09, Orca, PSI4 or CP2K. The following example generates Gaussian09 input files for hydrogen, carbon, nitrogen … WebbHirshfeld defined a weight function for each atom in a molecule, (1) where the individual ρati ( r) are spherically-averaged electron densities of the various atoms. In this manner the electron density of an atomic fragment can be defined as where ρmol ( r) is the molecular electron density.

Webb9 mars 2012 · The rigid-bond model [Hirshfeld (1976). Acta Cryst. A 32, 239–244] states that the mean-square displacements of two atoms are equal in the direction of the bond joining them.This criterion is widely used for verification (as intended by Hirshfeld) and also as a restraint in structure refinement as suggested by Rollett [Crystallographic … Webb11 maj 2024 · PLAT230 Type_2 Hirshfeld Rigid-Bond Test (Acta Cryst (1976),A32,239-244.
