| Abstract: | A CP MAS 13C NMR spectrum indicates that some liquid crystalline substances containing both cyclohexane and benzene rings have a local molecular motion around the benzene plane in the solid state, and the cyclohexane ring has a rigid conformation. The reorientational diffusion of the whole molecule is also observed in the solid state. |
