Abstract Dielectric relaxation behavior was examined for 4-4-n-pentyl-cyanobiphenyl (5CB) and 4-4-n-heptyl-cyanobiphenyl (7CB) under flow. In quiescent states at all temperatures examined, both 5CB and 7CB exhibited dispersions in their complex dielectric constant *() at characteristic frequencies c above 106 rad s1. This dispersion reflected orientational fluctuation of individual 5CB and 7CB molecules...
