Abstract
Pump-probe spectroscopy of the equilibrated solvated electron in metha nol and ethanol has been studied with similar to 300 fs time resolutio n. At low pump power the observed dynamics are assigned to s --> p exc itation and subsequent relaxation of a localized solvated electron. In contrast, at high pump power, two-photon absorption apparently produc es mobile ''conduction band'' electrons, which are subsequently trappe d and relax at a remote site from the initial equi:librated electron. The two-photon excitation is also observed to induce an ultrafast prot on-transfer reaction from the solvent.
