Abstract

ABSTRACT: The dielectric relaxation study for the hydrogen bonded binary system of polar liquid ethyl acetate in 1-butanol and 1-pentanol, has been carried out at 11 concentrations over the frequency range of 10 MHz to 20 GHz at 30°C using TDR. The least squares fit method has been used to obtain the static dielectric constant (ϵ0 ) and relaxation time (τ). By using dielectric parameters the excess permittivity (ϵ E ), excess inverses relaxation time (1/τ) E, Kirkwood Correlation factor (g) are also obtained to explore the hydrogen-bonded hetero-molecular interactions. Conformational analysis of the hydrogen bond between the two systems is supported by the FTIR spectra.
