Molecular Dynamics, Structure, and Phase Transitions in Liquid-Crystalline Media: ESR Studies

点击翻译按钮获取中文摘要

The objectives of this research are to explore the dynamic molecular structure of liquid crystals by using two-dimensional Fourier transform ESR and high-field ESR techniques. Detailed relaxation data are acquired to infer both the long-time and short- time molecular motions. The description of molecular motions in liquid crystals are enhanced by studies of transnational diffusion of the probes both at the molecular level and the macroscopic level. These studies are of special value for characterizing structure and dynamics of ordered systems.
