As compared to global hybrids, LRC functionals stabilize the occupied energy levels. Functionals whose range separation parameters are fit to thermochemical data tend to push even localized excitation energies somewhat higher, which slightly upsets the good performance of methods such as TD-PBE0 for valence excitation energies, leading to typical errors of 0.3-0.4 eV when LRC functionals are employed. CAM-B3LYP avoids this degradation by sacrificing the LRC constraint of 100% exact exchange at long range, meaning that υ xc (r) decays somewhat too quickly for a charge-separated excitation. For the tuned LRC-ωPBE functionals, which maintain correct asymptotic behavior, any upshift in the Errors in TD-DFT/def2-TZVPD excitation energies (with respect to established benchmarks), for a set of valence excitations using various functionals: (a) PBE, (b) PBE0, (c) LRC-ω GDD PBE, (d) LRC-ω IE PBE, (e) LRCω GDD PBEh, (h) LRC-ω IE PBEh, (g) HF-PBE, and (h) CIS.
