The permittivity and the dielectric loss for the ternary mixtures of diethylene glycol and acetonitrile / acrylonitrile in 1,4 dioxan have been obtained at an equimolar concentration at 35 c. The distribution parameter (α), the most probable relaxation time( τ ), the relaxation time for overall rotation of the molecule(τ1), the relaxation time for group rotation (τ2) and the excess dipole moment ( μ ∆ ) for various systems have been calculated by Higasi’s method and Cole-Cole method also utilized. Among the two systems, the size of the molecules is more for the mixture of diethylene glycol and acetonitrile. Negative values of dipolar increment are obtained for both studied systems and interpreted according to the results.
