Molecular geometry-dependent atomic charge calculation with modified charge equilibration method
We have improved a modified charge equilibration (MQEq) method for calculating the geometry-dependent distribution of atomic charges. In this paper, Ohno-Klopman, Ohno and DasGupta-Huzinaga equations are adopted to express the shielding effect, and the calculated atomic charges with these MQEq methods are in good agreement with those by the HF/6-31G(d,p) calculations for several organic molecules. These MQEq methods would be useful to estimate the charge distribution for large molecules.
