ROTATIONAL STATES OF POLAR MOLECULES IN RARE GAS CRYSTALS: POINT DIPOLE APPROXIMATION
Abstract
A study is made of the rotational states of small concentrations of polar molecules trapped in a rare gas lattice at low temperatures. The polar molecules are assumed to be effective point dipoles so that exchange forces are neglected. The dispersion interactions of each polar molecule with the rare gas host are found to be spherically symmetric, to a good approximation. Dipolar coupling is found to produce an effective rotational potential function at the site of each polar molecule. This potential, which acts as a small perturbation, is found to create a second order splitting of the free molecular rotational levels. Some numerical values of these splittings are given for the molecules HC1 and PH3. (Author)
