Photoinduced intermolecular electron transfer and off-resonance Raman characteristics of Rhodamine 101/N,N-diethylaniline

- Mechanism of PIET reaction process for the Rh101+/DEA system is investigated.
- The significant geometrical changes of the charge-transfer complex are explained.
- Forward Electron transfer from DEA to Rh101+∗ occurs with lifetime of 425-560 fs.
- Backward electron transfer occurs with a time constant of 46.16-51.40 ps.
- Intramolecular vibrational relaxation occurs with lifetime of 2.77-5.39 ps.
