Summary

Simplified formulæ involving only two force-constantsα andβ are given for the frequencies of the nine normal modes. Reasons are given for identifying the two force-constants as being respectively the products of the bulkmodulus and of the shearing modulus of the crystal by the distance between adjacent metal and halogen atoms. Calculations made on this basis of the nine frequencies of the rock-salt structure exhibit a highly satisfactory agreement with the spectroscopic data.
