Abstract:

An analytical method to describe tensor components of the dynamic electronic polarizability α_ii(R,ω) of diatomic molecules as a function of internuclear distance R and the frequency ω of external electromagnetic field is proposed. The method is based on calculations of upper and lower bounds for α_ii(R,ω). The bounds are calculated using the known functions of static polarizability α_ii(R,0) of a molecule, the limited number of energy levels E_m(R) of its excited electronic states, and the electric dipole transition moments (d_i)_0m(R). The method has been applied to calculate the dynamic electronic polarizability of H₂ molecule over wide ranges of R and ω values.
