| 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. |
