Structural properties in binary mixtures of polar molecules through microwave dielectric technique

摘要

The study of dielectric relaxation properties in a binary mixture of polar molecules has been carried out at temperatures 10, 15, 20 and 25°C using time domain Reflectometry technique. The dielectric properties of solute-solvent mixture in the microwave frequency range of 10 MHz to 30 GHz gives information about the formation of monomers and multimers as well as interaction between the molecules of the mixture. The dielectric parameters viz. static dielectric constant and relaxation time have been obtained by the least squares fit method using Debye equation characterized by a single relaxation time without relaxation time distribution.
