<title>Polarizability functions of HF and HCI molecules</title>

Abstract

The semiempirical method ofconstruction ofthe 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 e [0, oo).

Non-resonant dynamic stark control of vibrational motion with optimized laser pulses

“…As in the harmonic approximation, we retain the 1D description by once again assuming that the molecule is aligned with the field polarization direction along the z axis. The polarizability function will now be a semi-empirical function, 42 instead of the linear expansion we have been using thus far. Once again we assume the pulse carrier frequency is non-resonant and disregard any contributions to the molecular energy from the permanent electric dipole function.…”

“…To further illustrate this concept, a graphical representation of Γ (A 0 ,ω c , σ) for parameters selected to approximate the HCl electronic ground state 42,43 is shown in Fig. 1.…”
