Abstract :
Proton NMR was employed to study the nematic phases upon heating and upon cooling in PCH-3 (trans-4 (4-propylcyclohexy) benzonitrile). Our systematic measurements of the nematic order parameter and spin relaxations reveal the microscopic nature of the thermal hysteresis in this relatively low molecular weight nematic liquid crystalline material.
