The dielectric and infrared lattice dynamic properties of the cubic IV-VI compound semiconductors are reviewed. The values of macroscopic dynamic ionic charge are found to be appreciably larger than the corresponding values for alkali halide and zincblende type crystals. The large values of eT, which arise from the redistribution of electronic charge, provide further indication that the atomic dipole Lorentz field is the destabilizing factor responsible for the low values of omegaT in the IV-VI compounds.
