Caracterisation d'un milieu presentant une relaxation dielectrique par sa reponse a l'interface. Application a l'etude de quelques derives monosubstitues du benzene

Abstract

A new method (justified by permittivity measurement) is proposed to study dielectric relaxation by means of the interface air-dielectric response.

The characterization established here for a single relaxation (the distribution of relaxation times is represented by a Dirac function) can be used when a generalization is wanted for more complex cases (symmetric or asymmetric distribution function of relaxation times).

Application of this method to a series of mono-substituted benzenes is shown in this paper.
