    • note
    • We note that the first ∼250 fs of the data are sometimes subject to a coherence artifact which is not reproducible at different probe wavelengths. Thus, there is a small possibility that the coherence artifact masks spectral evolution of the solvated electron's absorption spectrum on these very short time scales. Experiments with shorter pulses should be able to resolve this issue.

    • note
    • We note that unlike the signal at 2 μm, which probes the solvated electron, the 575-nm transient shows a polarization dependence, suggesting that the visible-absorbing species undergoes rotational diffusion on a tens or hundreds of picoseconds time scale.

    • note
    • The excitation intensities used for the pump-probe experiments in this study could be varied by only a factor of ∼10 from ∼1 to ∼10 mJ/cm2; lower intensities resulted in signals too small for effective signal averaging.

    • The diffusion constant of the solvated electron in THF was calculated by using the Einstein relation, D = (kT/e)μ, where e is the elementary charge and μ is the mobility of the electron.

    • note
    • 1 decreases slightly at bluer excitation wavelengths, consistent with the idea that additional internal electronic relaxation is required before detachment can occur, as suggested by the simulations in Ref. 29.
