Abstract:
We present the first measurement of the vertical binding energy (VBE) of a hydrated electron in bulk water by the time-resolved photoelectron spectroscopy (TRPES) of the charge-transfer-to-solvent (CTTS) reaction in aqueous NaI solution. Our best estimate of VBE is 3.27 +/- 0.10 eV for H(2)O and 3.20 +/- 0.10 eV for D(2)O.
