Abstract : The dielectric properties of polar solvents are considered within the context of generic mean spherical approximations. Given the molecular diameter in a spherical representation, the dipole moment, and molecular polarizability, the static permittivity of such a solvent is estimated on the basis of the Wertheim polarization parameter, and a stickiness parameter which accounts for other electrostatic features of the bulk system and non-sphericity of the actual solvent molecules. The stickiness parameter is related to the magnitude of dipole-dipole interactions for a series of solvents with the same polar group. This model is also used to estimate the Kirkwood structure factor. The values obtained are in excellent agreement with structural features of these systems obtained from experiment.
