Abstract
Information on molecular dynamics of the nematic liquid crystal 4-n-pe ntyl-4'-cyanobiphenyl (5CB) doped with the dyes DMANS and DMANAB has b een obtained by luminescence and Raman measurements. Temperature depen dences of reorientational correlation times are not the same for diffe rent molecular motions. Mechanisms responsible for the marked deviatio n of the time values obtained by different optical methods are discuss ed.
