Deuterium NMR spectroscopy has been used to investigate the director dynamics in the smectic A phase of perdeuteriated 4-octyl-4′-cyanobiphenyl-d 25 (8CB-d 25), where the director was aligned by an electric field. The electric field direction made an angle of 44.7° with the magnetic field in order t...
