Abstract
For transition-metal compounds the scattering of metal d states into empty nonmetal p states is suggested to be the mechanism responsible for the soft-mode anomalies found in the phonon spectra. This idea is confirmed by investigating the effects of carbon vacancies on the electronic structure of NbC using the X alpha scattered-wave method.Keywords
