Polarizability functions of HF and HCI molecules

The semiempirical method of construction of the electronic polarizability functions for heteronuclear diatomic molecule in the piecewise-continuous form is discussed. The polarizability functions obtained have true asymptotic behaviour as for small as for large internuclear separations R and describe correctly the polarizability of a molecule in a vicinity of the equilibrium internuclear distance. To describe the polarizability functions for large separations, the DID interactions of atoms have been taken into account, and the exchange interactions of atoms have been considered by asymptotic methods. The method has been applied to calculate the polarizability functions of HF and HCI molecules in a range R ∈ [0,∞).© (2006) COPYRIGHT SPIE--The International Society for Optical Engineering.
