Abstract
The dielectric properties of solutions of the liquid crystals with (CH2) spacers and nitrile groups in molecules in weakly polar nematic diluent were studied. In the frequency range of a.c. electric field (102−108)Hz the dispersion of complex dielectric permitivities ε| in nematic phase were investigated. From the dielectric spectra of ε|, the relaxation frequencies fRwere obtained for each of the investigated substances. It was shown that fR increases with the (CH2) spacers length of the central alkyl chains of molecules.
