The structure and orientational order of molecules in nematic liquid crystal phases

The structure and orientational order of molecules in nematic liquid crystal phases
The structure and orientational order of molecules in nematic liquid crystal phases

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.

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.
