Abstract
The effect of a polarizable impurity atom on the frequency of optical vibrations of a crystal is calculated. The impurity-lattice interaction is treated by considering the lattice polarization as discrete in contrast to earlier methods based on the continuum approximation. In the appropriate limit, our result goes over exactly to the result of the continuum theory.Keywords
