Electron Photodetachment from Halide Ions in Solution: Excited-State Dynamics in the Polarization Well

The electronic relaxation and photodetachment dynamics of an electron originating from an aqueous iodide ion have been studied using femtosecond absorption spectroscopy. The results indicate the importance of an upper excited charge transfer to solvent (CTTS) state, of odd parity, in the potential w...

Zusammenfassung:	The electronic relaxation and photodetachment dynamics of an electron originating from an aqueous iodide ion have been studied using femtosecond absorption spectroscopy. The results indicate the importance of an upper excited charge transfer to solvent (CTTS) state, of odd parity, in the potential well of the solvated ion. The upper excited CTTS state, which is accessed by two-photon excitation, relaxes in
