Abstract The parameters of the deformation‐dipole model which were determined in the preceding article of this series for 15 compounds with zincblende structure are now systematized into a regular scheme. It is found that short‐range forces between first neighbours vary as monotonic functions of interatomic distance and that static ionic charge varies linearly with Pauling's ionicity. The physical meaning of these regularities is discussed.
