Abstract

The behavior of the dipole moments of molecular transitions is analyzed as a function of the internuclear distance R and it is shown that for allowed transitions the departure of the dipole moment from the value for the unperturbed atom varies as [Formula Presented] with a coefficient that can be obtained from the dynamic polarizability of one atom evaluated at the unperturbed transition frequency of the other.
