Abstract

The paper presents the results of the measurements of the dielectric relaxation of nematic 6-CHBT performed for different values of the angle between the directions of the macroscopic orientation of the same (director n) and the probing electric field E. Analysis of the evolution of the relaxation spectrum from (epsilon) _(parallel)^*((omega) ) (E (parallel) n) to (epsilon) _{(perpendicular})^*((omega) ) (E (perpendicular) n) allowed one to explain the inconsistency in the molecular interpretation of the spectra. A model of the molecular dynamics in the oriented nematics is proposed.
