Configuration of the electronic terms. The dashed circles , the solid circles and are the equipotential curves of the ground, excited, and charge transferred states, correspondingly. and are the reaction coordinates of the optical transition and PET, respectively. The crossing line between the terms and is labeled as . are coordinates of the initial positions of term minima. The shaded ellipses show the initial positions and the forms of the wave packets produced by the pump pulses with the frequencies at half the absorption band maximum.
