Abstract
A theory of the dielectric susceptibility of polar gases adsorbed on ionic solids is presented. The rotational oscillator model of an adsorbed polar molecule is used, and dielectric loss is assumed to occur by phonon emission and absorption. For linear coupling of the rotational oscillator to the lattice vibrations, an exact solution is found using diagrammatic perturbation theory at finite temperature. In this model, appreciable loss is only found if the density of phonon states near the classical oscillator frequency is reasonably large, and it is suggested that this is to be expected in situations where the rotational oscillator model is valid. The method can be extended to more complex adsorbate–lattice interactions.
