Simulated absorption spectra in Fig. include just three excited states per snapshot, representing the s → p transitions of a particle in a quasi-spherical cavity. Spectra in Fig. include additional excited states and exhibit a "blue tail" at higher excitation energies, which is characteristic of the spectrum of e -(aq). These spectra show, on the one hand, how exquisitely tunable TD-DFT excitation energies are with respect to the frac- tion of HF exchange, as the maximum in the absorption spectrum is shifted by ≈ 1 eV from α = 20 to α = 70. Regardless of how many states are included in the calculation, 20% exact exchange affords a spectrum that peaks much too far to the red, likely as a result of CT character in the excited states. Values α = 40-50 afford a much better match to the experimental absorption maximum. Because the original QM/MM trajectories were performed using a different functional (BLYP with a self-interaction correction), we do not want to overemphasize which particular value of α matches the experimental absorption maximum, as this is certainly affected by the solvent structure that is obtained from the ground-state molecular dynamics. That said, values α 60 are clearly too strongly blue-shifted. This reinforces the view that BH&H-LYP (α = 50) is a good choice for TD-DFT applications.
