Abstract

The molecules in nematic liquid crystal phases move rapidly but not randomly producing partial molecular orientation described by sets of order parameters. The molecules of pure liquid crystals are flexible by virtue of bond rotational motion, which has a profound effect on the properties of the liquid crystal phase. NMR spectroscopy can study these phenomena by 1H, 2H and 13C resonances in the nematic and paranematic phases.

向列相液晶中分子的结构和取向顺序

向列相液晶中的分子运动迅速，但不是随机的，产生由一组有序参数描述的部分分子取向。纯液晶分子由于键的旋转运动而具有柔性，这对液晶相的性质有深远的影响。核磁共振波谱可以通过向列相和副相的1H、2H和13C共振来研究这些现象。

期刊介绍： Progress in Nuclear Magnetic Resonance Spectroscopy publishes review papers describing research related to the theory and application of NMR spectroscopy. This technique is widely applied in chemistry, physics, biochemistry and materials science, and also in many areas of biology and medicine. The journal publishes review articles covering applications in all of these and in related subjects, as well as in-depth treatments of the fundamental theory of and instrumental developments in NMR spectroscopy.
