Abstract
The frequencies are calculated for the local vibrational modes of Vk centres in alkali halides by considering a cluster of relaxed ions around the defect embedded in a non-primitive unit cell of the lattice, and using the shell model. The results give excellent agreement with values obtained from Raman spectra. The vibrational spectrum obtained can be used to calculate some thermodynamic properties of the defects and some illustrative calculations are reported.
