Paper Abstract

Hydrogen Deuteride is a molecule with a small permanent electric dipole moment (about 0.8 x 10-3 Debye) and a corresponding weak vibro-rotational spectrum. Wick (1935) predicted the existence of the HD dipole moment, entirely due to non-adiabatic effects, coupling the electronic and nuclear motion. This molecule is of special interest for astrophysical studies and the smallness of its dipole moment has also stimulated fundamental studies on collision induced dipole moments.
