Polarizability and molecular radius of dimethyl-sulfoxide and dimethylformamide from refractive index data

Abstract

Densities and refractive indicies of dimethylsulfoxide and dimethylformamide were measured at various temperatures and wave-lengths. Polarizabilities and molecular radii were calculated on the basis of Böttcher's theory of electric polarization and compared with the molecular radii evaluated from the molar volumes of the liquids and from geometrical considerations.
