摘要：

The dielectric spectrum of n-heptyl-cyanobiphenyl (7CB) and n-heptoxy-cyanobiphenyl (70CB) are reported over a frequency range up to 18 GHz and over a temperature range well into the isotropic phase. Two relaxation processes are observed in the isotropic phase of both compounds, as well as in the nematic phase (when measurements are made parallel to the nematic director). Possible mechanisms for the two relaxation processes are discussed.
