Abstract
The principal objective is to determine and study the dielectric relaxation characteristics of primary and secondary acetates such as Methyl Acetate, Ethyl Acetate, Isopropyl Acetate, n-Butyl Acetate and Amyl Acetate with complex permittivity spectra (CPS), which has been measured in 0.1 < ν/GHz < 50 frequency range using Time Domain Reflectometry and fitted to Debye model. Static dielectric permittivity, relaxation time and Kirkwood correlation factor have been determined using non-linear least squares fit method. Association of molecule and chain length affects on dielectric relaxation process in esters. The Arrhenius behavior has been revealed by means of temperature dependent value of relaxation time.
