Abstract
We have investigated the optical excitation of solitons and charge tra nsfer excitons in polymer chains by solving the equations of motion fo r the reduced density matrix and the lattice displacement simultaneous ly in time. Electron-phonon coupling leads to polaron-exciton formatio n which can be identified in transient pump-probe signals.
