Range-separated hybrid (RSH) functionals, 1 including LRC-ωPBE and a screened RSH approach (sRSH-ωPBE) that respects asymptotic behavior within a low-dielectric crystal medium, 331 exhibit a much greater degree of FE character, with amplitude along the diagonal of the Ω matrix. There is still some charge-separation character in these cases although it is asymmetric, indicative of localized (directional) CT. In centrosymmetric systems, localized CT is not possible due to symmetry and dipole moment changes vanish for the same reason, but Ω heat maps can still be used to infer charge-separated character. To examine excitonic states in conjugated polymers of interest for organic electronics, Tretiak and coworkers have made extensive use of atomic partitions of the TDMs from semi-empirical electronic structure calculations. (This analysis has sometimes been ported to all-electron TD-DFT calculations without recognition of the need to consider the AO overlap matrix. ) Neglecting S or else using an orthogonalized minimal basis, there is little distinction between l A→B in Eq. ( .3) and Ω A→B in Eq. (4.9), if normalization is ignored for the purpose of inferring spatial correlations between particle and hole. Tretiak and co-workers use slightly modified CT indices, namely
