摘要

In this article we report on temperature dependence of Davydov splitting value FTIR spectra study for the in-phase CH_2 rocking vibrations of methylene chains in liquid crystalline cholesteryl myristate (CholC_(14)) for the temperature region from 100 K to the crystal melting point. A statistic-dynamic model in terms of stochastic equations is used to explain the obtained results. We take into account the damping of vibrational excitons on orientational defects due to excitation of conformational, librational and position disorder degrees of freedom. The explicit expression for the theoretical dependence of Davydov splitting value of vibrational exitones on temperature was considered. Good agreement between the experimental data and the results of such dependence computer simulation is observed.
