Molecular interaction at 250C temperature of acetonitrile with 1, 2 dichloroethane mixture using time domain reflectometry

The dielectric parameters have been determined for acetonitrile(ACN) with 1,2 Dichloroethane(DCE) mixture at temperature 250C in the frequency range of 10 MHz to 20 GHz using time domain reflectometry (TDR) for 11 different concentrations of the system. The Kirkwood correlation factor (gf) and Kirkwood averaged effective correlation factor (geff) of the mixture has been determined. The static dielectric constants for the mixtures have been fitted with the modified Bruggeman model. The investigation shows that there is systematic change in dielectric parameters of the system with change in concentration.It shows that the antiparallel alignment and strong interaction between the constituent molecules of the ACN-DCE mixture.
