That said, the accuracy obtained for these higher-lying transitions is not as good as what we reported for Kedge (1s → LUMO) transitions, and this conclusion holds across a variety of XC functionals. It also holds for the ∆SCF approach, where the best-performing functionals (SCAN, SCAN0, and B3LYP) see their MAEs increase from 0.3 eV for 1s → LUMO transitions to 1.2 eV for the higher-lying excited states. The two LRC functionals actually see their errors become slightly smaller for the higher-lying transitions.
