Summary
Expressions for the frequencies of the nine normal modes of the zinc sulphide structure are derived in terms of 10 force-constants taking account of the interaction of each atom with its 16 nearest neighbours. The formulæ, after simplification contain only six constants which are further connected by two additional relations.
