Polarizability of a diatomic molecule as a function of internuclear distance
- Kuznetsov Physicotechnical Institute, Tomsk (Russian Federation)
A semiempirical method for calculating the polarizability of diatomic molecules in the entire range of possible values if their internuclear distance is proposed. The method is based on the functional dependence of the polarizability of a molecule on the internuclear distance R in the region of small R obtained in the previous paper, the known polarizabilities and their derivatives at the equilibrium position of the molecule nuclei, and also results of the model of polarized of atoms valid for large internuclear distances. The efficiency of the proposed method is tested for the hydrogen molecule for which reliable polarizability values are available in the wide range of internuclear distances. The proposed method is used for calculating the polarizabilities of the nitrogen and oxygen molecules. 17 refs., 6 figs., 1 tab.
