Abstract
We study the stability of the soliton-like polaron states in a molecul ar chain by means of a perturbation approach. We demonstrate that, und er the influence of thermal fluctuations in the host lattice, the soli ton gradually decays into delocalized ('excitonic') states. The solito n lifetime depends strongly on temperature and the coupling strength.
