Dielectric relaxation study of N-methylformamide in 1, 4-dioxane solvent using time domain reflectometry technique up to 30 GHz

Mahajan, Gajanan Ramrao; Kumbharkhane, Ashok C

Abstract

Complex dielectric permittivity has been determined for the mixture of N– methylformamide (NMF) – 1, 4 –dioxane (DX) with various concentrations in the frequency range from 10 MHz to 30 GHz by time domain reflectometry (TDR) at different temperatures. The Luzar theory has been applied to compute Kirkwood correlation factors for the mixtures. It adequately reproduces the experimental values of static dielectric constants. The Bruggeman model for the non linear case has been fitted to the dielectric data of the binary mixture.
