Popis: | We study the possible influence of polaron effect on the phonon spectrum in quasi-one-dimensional molecular chains. It was found that polaron induced phonon correlations may lead to the characteristic modifications of the phonon frequencies and speed of sound which shows specific temperature dependence for particular type of polaron.
