Abstract
The dynamic Stokes shift of the donor-acceptor compound, PIDMP, in its lowest excited charge transfer state has been studied in a series of ethereal solvents at room temperature with a time resolution of about 300 fs. By means of the fluorescence upconversion method dynamic Stoke s shifts of up to 2400 cm(-1) on a subpicosecond time scale have been resolved. The observed dynamic Stokes shifts are due to solvation rela xation for which the kinetics is determined by rotational diffusion mo tions of the solvent molecules.
