Interactions in the binary mixture of dimethyl phthalate with triethylamine have been studied through the orientation of dipoles using dielectric polarization process. This vital information could be obtained from dielectric measurements by virtue of the influence of local order and the overall dipole moment. The information regarding orientation of electric dipoles in polar liquids was obtained from Kirkwood correlation factor, effective correlation factor, and corrective correlation factor. The Bruggeman parameter determination confirms the molecular interaction between the constituents of the binary mixture and thermo dynamical excess parameters were also measured for analysis for three different temperatures (303K, 313K and 323K).
