Having described this manifold of excited states, we conclude this section by presenting the CTN-based analysis of their corresponding wavefunctions (pAB is partitioned into CaO and the rest). Here, CTNs can be interpreted as the number of electrons transferred between the OCC and AB moieties-perfectly decoupled localized transitions can be identified by zero CTNs. Fig. shows the CTNs and the state energies. We highlight the following observations:
