摘要

利用介电弛豫光谱(DRS)研究了纯环己醇(CYN)、二甲苯及其二元溶液在10 MHz ~ 30 GHz微波频率范围内的协同动力学。用协同结构域(CDs)的概念解释了CYN-CYN、cyn -二甲苯分子的动力学。在cyn -二甲苯二元溶液中，由于分子间的自缔合和键的断裂而存在偏差。柯克伍德相关因子通过氢键对具有多种交换的CDs进行鉴定。Luzar模型提供了相当好的εo的定性值，因此理论计算值与实验结果比较比较好。

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 selfassociation 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.
