Abstract:
Birefringence in the mesophase of 4-cyano-4′-n-pentylbiphenyl (5CB) was measured directly under a magnetic field (1200 and 2000 gauss) as a function of temperature with field parallel and perpendicular to the optical axis. Electrical dinole moments of 5CB and benzonitrile were calculated with the Mechetti-Barón equations from measurements at three temperatures. Molecular geometries were examined with a semiempirical procedure (AMPAC). The results suqgest that thermal stirring and internal rotations appear to overcome orientational effects of the applied field. © 1989.
