Abstract
The polarizability volumes in a number of inorganic crystals have been evaluated in two routes: by indices of refraction (Lorenz-Lorentz equation) and by relative dielectric permittivities (Clausius-Mossotti equation). The compounds include binary and complex oxides, fluorides as well as chalcogenides. The polarizability volume for each compound has been normalized with the volume occupied by one “molecule” or “formula unit” in the crystal. The relevant crystal structures have been restricted to those of the most stable polymorphs under standard conditions. It has been found that the polarizability volumes based on the indices of refraction account for a part (mostly 40–60 %) of those calculated using relative dielectric permittivities. The distribution of the polarizability volumes in respect to the orders of the point groups of the space groups has been also discussed.
