For excitation energies, TD-BH&H-LYP exhibits superior results in cases where TD-B3LYP fares poorly. Examples include core-to-valence excitations at elemental K-edges, which effectively a type of CT state, as well as transition energies for other charge-separated states including Rydberg excitations. For these systems, 50-60% exact exchange affords the best results. The BH&H-LYP functional also affords a reasonable absorption spectrum for the hydrated electron, a problem that is exquisitely sensitive to the fraction of exact exchange. In contrast, functionals with ≈ 20% HF exchange afford spectra for e -(aq) that are significantly red-shifted, due to CT contamination. Conversely, B(α)LYP with 60% HF exchange affords a significantly blue-shifted spectrum.
