Abstract
Results are reported from a light scattering measurement in the uniaxi al nematic phase in the thermotropic liquid crystal octylcyanobiphenyl , a material which does not exhibit a biaxial phase. In addition to a slow Goldstone mode associated with twist fluctuations, a fast mode wh ose relaxation time is independent of both wave vector and temperature has been observed. The possible origins of this relaxation are discus sed.
