Study of Co-operative Dynamics in Cyclohexanol-Xylene Solutions using Dielectric Relaxation Spectroscopy


Cooperative dynamics in pure cyclohexanol (CYN), xylene and their binary solutions have been studied using dielectric relaxation spectroscopy (DRS) in 10 MHz to 30 GHz microwave frequency range. The dynamics in CYN-CYN, CYN-xylene molecules have been explained using concept of cooperative domains (CDs). Deviations in CYN-xylene binary solutions exist due to braking and making of bonds as well as self-association among the molecules. Kirkwood correlation factor authenticates CDs with diverse exchanges through hydrogen bonding. Luzar model offers moderately decent qualitative values of εo such that the theoretically calculated values found relatively good in comparison with experimental results.
