Abstract
The Phillips—Van Vechten dielectric theory of binary tetrahedral compounds and Levine's bond-charge model are formulated in terms of macroscopically defined linear and nonlinear bond polarizabilities. This formulation allows the determination of the linear and nonlinear optical properties of tetrahedral solids. As an illustration, the case of ternary compounds with chalcopyrite structure is considered. Theoretical and experimental results are in good agreement.
