Thermal hysteresis was observed, upon heating and cooling, in our proton nuclear magnetic resonance studies of the nematic phases in PCH-3 [trans-4 (4-propylcyclohexy) benzonitrile]. The microscopic nature of the hysteresis in this liquid crystalline material was revealed by our systematic measurements of the nematic order parameter and the spin-lattice relaxation.
