9700680 Fung This project involves the further development and implementation of new nuclear magnetic resonance (NMR) techniques and their application to the study of liquid crystals of current interest, viz., ferroelectric and antoferroelectric systems. The NMR data will be combined with Fourier Transform Infrared (FTIR) results to be generated through a collaboration with colleagues at the University of Colorado. This comprehensive approach will be used to advance a theoretical modeling approach that will contribute to the understanding of molecular conformations and interactions on the phase behavior of liquid crystals, and perhaps to the formulation of new low-viscosity nematic mixtures. %%% The synthesis and properties of new liquid crystal systems are playing an increasingly important role in advancing a number of applications areas that include new materials for infrared and microwave liquid crystal modulators, and fast-switching liquid crystal displays. Furthermore, since the phase behavior of liquid crystal mixtures formulated to optimize certain materials properties is often complicated and unpredictable, the focus of these studies should advance significantly the use of these systems for industrial uses. ***

小行星9700680 该项目涉及进一步开发和实施新的核磁共振（NMR）技术及其在当前感兴趣的液晶研究中的应用，即，铁电和反铁电系统。 核磁共振数据将与傅里叶变换红外（FTIR）结果相结合，通过与科罗拉多大学的同事合作产生。 这种全面的方法将被用来推进理论建模方法，这将有助于了解分子构象和相互作用的液晶相行为，并可能制定新的低粘度混合物。 新液晶体系的合成和性能在推进包括红外和微波液晶调制器以及快速切换液晶显示器的新材料在内的许多应用领域中发挥着越来越重要的作用。 此外，由于为优化某些材料性质而配制的液晶混合物的相行为通常是复杂和不可预测的，因此这些研究的重点应该大大促进这些系统在工业上的应用。 ***
