Dielectric relaxation of propan-1-ol with chlorobenzene, 1,2-dichloroethane, and dimethylene chloride at (288, 298, 308, and 318) K using time-domain reflectometry technique

The values of complex permittivity of molecules containing chlorine with propan-1-ol binary mixtures have been determined over the frequency range of (0.1 to 20) GHz, at temperatures of ( 288, 298, 308, and 318) K, using the time-domain reflectometry (TDR) method for 11 molalities of each molecule containing chlorine with propan-1-ol system. The dielectric relaxation in these systems can be described by a single relaxation time using the Havriliak and Negami model. The static dielectric constant (epsilon(0)) and relaxation time (tau) have been obtained by fitting experimental data with the Havriliak-Negami equation.
