Study of Dielectric Properties of Aqueous Solution of Nicotinic Acid Using Time Domain Technique

The present paper represents, the work undertaken of the study of dielectric constant of aqueous solution of Nicotinic acid for various concentrations. The time domain reflectometry techniques used for the study in the frequency range from 10MHz to 30GHz. The relaxation time (), The static dielectric constant (), dielectric constant at higher frequency (-) and thermodynamic parameters of mixture of Nicotinic acid with water have evaluated at 250c temperatures. The thermodynamic parameters of mixed solvent such as the enthalpy of activation (H) and entropy of activation (S) are also evaluated.
