Abstract
THE well-known method of computing the electric moments of solute molecules due to Debye makes use of the Clausius-Mosotti formula for the dielectric constant of a mixture. Whereas the analogous Lorenz-Lorentz formula for the refractive index of a mixture is probably very accurate1, the Clausius-Mosotti formula is at the best a rough approximation because it ignores the force on a polar molecule due to the surrounding molecules being polarised by the molecule considered.
