Abstract

We report on the observation of the solvation shell rearrangement after abstraction of the electron from aqueous I - in a laser pump/X-ray probe experiment by recording the X-ray absorption L 1 - and L 3 -edge spectra, 50 ps after laser excitation. The L 1 -edge spectra clearly identify the I 0 neutral species after excitation and suggest a substantial amount of back-transfer of charge... (More)

We report on the observation of the solvation shell rearrangement after abstraction of the electron from aqueous I - in a laser pump/X-ray probe experiment by recording the X-ray absorption L 1 - and L 3 -edge spectra, 50 ps after laser excitation. The L 1 -edge spectra clearly identify the I 0 neutral species after excitation and suggest a substantial amount of back-transfer of charge from the solvent species. Both edge spectra point to a significant rearrangement of the solvation shell around I 0 .
