摘要: Abstract The half-width temperature dependence of various bands from IR spectra different smectic and cholesteric liquid crystals has been investigated. activation energy for rotational diffusion Uoτ is determined in smectic, isotropic phases. A relationship between the value mesophase stability was found.
