The molecular interactions between the polar systems of p-hydroxy dodecyl benzoate(12HB) and Isoproponal for various volume fractions were studied at room temperature to determine the frequency dependent complex dielectric permittivity using Abbe’s refractometer for optical (1015Hz) frequency, the cavity perturbation technique for the microwave frequency at 10GHz (X-Band),and LCR meter at 1KHz. The Relaxation times and dipole moments for the binary mixtures were calculated using Higasi’s method and compared them with theoretical values. The formation of Hydrogen bond between the polar system as caused for the variations in the dipole moments and relaxation times in binary mixtures for different concentrations. The conformational analysis of the formation of hydrogen bond between dodecyl hydroxyl benzoate and isopropyl alcohol is supported by the experimental FTIR spectral studies and theoretical computational methods.
