重水素化シクロヘキサン環を持つ液晶化合物の重水素NMR

抄録

The first example of ²H-NMR study of cyclohexane containing liquid crystals is reported. The observed spectrum is consisted of a superposition of discrete quadrupolar doublets associated with the axial and equatorial deuterons, and is used to evaluate the orientational order parameters of the cyclohexane ring. Temperature dependence of the orientational order parameter, its biaxiality, and the alignment angle of the molecular principal axis is discussed.
