The formalism of the deformable‐bond approximation, described in the preceding article of this series, is now applied to 15 compounds with zincblende structure. The phonon dispersion curves and densities of phonon spectra are calculated for ZnS, ZnSe, GaP, GaAs, InSb, SiC, GuCl, and CuI, the method developed for determination of 15 parameters characterizing the model is discussed. Analogous results obtained with an 11‐parameter version of the rigid ion model are presented for comparison.
