Abstract

Based on the united atom model and the LS-coupling approximation, dipole moment functions were calculated for some diatomic molecules at small internuclear separations R. Families of molecules belonging to united atoms Li(2 S), Na(2 S), B(1 P), Al(1 P), and O(1 D) were considered. It was shown that dipole moment functions at R → 0 satisfy the asymptotic dependence μ(R) =AR 3. The regularities in the behavior of the functions μ(R) were determined depending on the electronic state and nuclei charges of molecules. The obtained systematic features are in good agreement with the results calculated for molecules whose united atoms are in groups II, IV, V, VII, and VIII of the Periodic Table.
