A generalization of the Clausius-Mossotti equation to include a permanent moment [[[vector].[micro]].sub.e] is summarized in what is called the Debye equation that is valid for gases and dilute solutions:
The Debye equation could be used to estimate the permittivity of a gas if both the polarizability and the dipole moment were known from experiment.
Onsager included the effects of the reaction field into the local field and obtained the following relationship for the static field that, and unlike the Debye equation, can be used to model the dipole moment of some pure liquids:
In some studies, least squares fitting technique has been applied to reduce Gabriel's 4-pole Cole-Cole equations to simpler 2-pole Debye equations [13-15].
