heal.abstract	Dielectric permittivity of 4-n-octyl-4-cyanobiphenyl (8CB) is measured by a shearing Couette cell in the nematic and isotropic phase. Correlation factors are calculated according to Bordewijk and De Jeu for the nematic mesophases and according to Kirkwood for the isotropic liquid. Activation energy for the nematic reordering is measured dielectrically and the viscous activation energy is measured through the viscometric capability of the shearing cell. A potential barrier of 0.18 eV due to close range intermolecular forces is then obtained.	en
