An empirical method for the calculation of average molecular polarizability is introduced. In this method, the effective atomic polarizabilities are described as a function of net atomic charges which are obtained with the modified partial equalization of orbital electronegativity (M-PEOE) method. The effective atomic polarizability is derived with the aid of the Thomas-Fermi model of multiply-charged spherical ions. The calculated polarizabilities agree well with experimental data. Nonbonded potential parameters are also calculated as a function of net atomic charges from the effective atomic polarizabilities.
