Dielectric constants of homogeneous mixture

A new simple formula for the dielectric constants of homogeneous mixtures is derived. This formula contains expression (ε1/3-1) instead of the usual quantity (ε-1)/(ε+2) (Clausius-Mosotti, Debye). Similarly, function (n 2/3-1) replaces (n 2-1)/(n 2+2) in the Lorentz-Lorenz formula. The application of the resulting modified definitions of molar refraction and of molar polarization is discussed on the basis of experimental data. The determination of dipole moments of organic molecules can be improved by the use of this new formula. No additional parameters are needed, and calculations are as simple as in the usual Debye method.
