Abstract: Complex permittivity at 9.1 GHz, static permittivity at 455 kHz and refractive index at optical frequency of methanol, ethanol, 1-propanol, 2-fluoroaniline, 4-fluoroaniline and their binary mixtures have been measured at a single temperature (30°C) in dilute solution of non-polar solvent benzene. The measured values of permittivity and dielectric loss have been used to evaluate distribution parameter () and relaxation times 0, (1), (2) and dipole moment( ). The variation of relaxation time versus concentration suggests solute-solute/solute-solvent type of association through hydrogen bonding.
