Abstract:  The dielectric relaxation studies of propan-1-ol with alkyl benzoates (methyl benzoate and ethyl benzoate) have been carried out, for various mole fractions at different temperatures, using LF impedance analyzer, Plunger method and Abbe’s refractometer in radio, microwave and optic frequency regions, respectively. Kirkwood effective correlation factor, corrective Kirkwood correlation factor, Bruggeman parameter, relaxation time and thermo dynamical parameters are calculated using the experimental data. Conformational analysis of the formation of hydrogen bond in the equimolar binary mixture systems of propan-1-ol with alkyl benzoates is supported by experimental and theoretical FT-IR values.
