Paper Abstract

Complex dielectric permittivity measurements performed for right handed (s) 4-(2-methylbutyl)-4'-cyanobiphenyl (CB15) in frequencies from 0.1Hz till 100kHz are presented. The phase sequence observed on cooling differs form that observed on heating: on cooling only an isotropic liquid and a glassy phase have been observed while on heating the glass transforms to a viscous liquid that crystallizes around 245K. On further heating the crystal melts to form the isotropic liquid at about 280 K. Temperature dependence of relaxation time is found to be of the Vogel-Fulcher-Tamman type.
