A new model explaining fast charge separation from optically achievable charge transfer (CT) states in molecular complexes is suggested. The idea is based on the assumption that the polarization reaction to the charges generated in the initial CT state can be divided into two evolution paths along fast and slow reaction coordinates. A possibility of the charge transfer rate enhancement by the oscillations of the system along the slow polarization coordinate is demonstrated. (C) 2002 Elsevier Science B.V. All rights reserved.
