Abstract : The dielectric and infrared lattice dynamic properties of the cubic IV-VI compound semiconductors are reviewed. The values of macroscopic dynamic ionic, e*T = δMT-δuTE are found to be appreciably larger than the corresponding values for alkali halide and zincblende type crystals. The large values of e*T, 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 ωT in the IV-VI compounds.
