Relative permittivity or static dielectric constant is a macroscopic and intrinsic property thatprovides important information about molecular associations and geometrical structure ofmolecules [1,2]. The nature and strength of interactions in solutions, over a range ofcomposition or temperatures, can be obtained using dielectric analysis [3,4].In this work, we present permittivity data for the binary systems of AC and DMSO with AAat T=298.15 K. In order to obtain valuable information about heterogeneous interaction(interactions between the unlike molecules), the Kirkwood correlation factor, the Bruggemandielectric factor and the excess permittivity were calculated.
