Abstract
A noncentral second neighbour ionic model is proposed for calculating frequency wave vector dispersion relations for the normal modes of vibrations for zinc and cadmium tellurides crystallizing in the zinc blende structure. The model takes into account the change in energy owing to rotation of bonds. The calculated phonon frequencies show a reasonably satisfactory agreement with the available optic data.
