A numerical study of the Davydov soliton dynamics in a thermalized cyclic molecular chain is performed. Account is taken of the effect of thermalized molecular vibrations within the scope of the quantum‐mechanical theory. It is shown in contrast to results of a number of works, where account of the thermal vibration effect is taken within the framework of the classical model, that using the quantum‐mechanical description the thermal vibrations not only don't prevent but also favour autolocalization of intramolecular excitation.
