摘要:
AbstractSolitary excitations due to the combination of an electronic excitation with intramolecular (both totally symmetric and nontotally symmetric) vibrations are shown to take place in molecular chains. Two cases are considered: a) when the molecules of the chain are fixed at their equilibrium positions and b) when the chain molecules are oscillating. In the second case solitary bound states of the chain deformation and the exciton‐intramolecular excitation can exist and propagate along the chain. The parameters of the solitons and the energy of the system are calculate
