For these heavier elements, B3LYP/CIS consistently overestimates the excitation energies while CAM-B3LYP/CIS overestimates them albeit to a lesser extent. This is particularly striking because the two methods employ corrections to the core-orbital energies that are similar in magnitude for second-row elements, illustrating the need for a row-specific correction. Either way, the errors are significantly smaller as compared to conventional TD-DFT with either B3LYP or CAM-B3LYP, by ∼ 50 eV on average. For the transition metal complexes, CAM-B3LYP/CIS is slightly more accurate than TD-SRC1-r2.
