Group theoretical methods have been applied for obtaining the normal oscillations of the diamond structure on the basis of a 16 atom cell as the repeating unit. It is shown that besides the translation, there are eight normal oscillations one of which is threefold degenerate, two of which are fourfold degenerate, three of which are sixfold degenerate and two of which are eightfold degenerate. Expressions are derived for the corresponding normal frequencies by postulating suitable potential energy functions.
