Figure correlates Λ against errors TD-B3LYP calculations, comparing the CMO and NTO representations within the same plot. For several of the CT states, Λ CMO is numerically quite different from Λ NTO and this is highlighted for a few of the CT transitions. A threshold value Λ CMO = 0.3 that was suggested by Tozer and co-workers for calculations involving hybrid functionals works reasonably well in the CMO representation but rotation into the NTO representation moves a few of these transitions across the line. Furthermore, not all of the shifts between Λ CMO and Λ NTO are in the same direction.
