These can be used to characterize the nature of an excited state, in both qualitative and quantitative terms. Although many of these analysis and visualization methods have been around for a long time, only occassionally have the connections between them been discussed, and often in a general form for correlated wave functions with arbitrary levels of excitation. This obscures certain simplifications that are possible for CIS-and TD-DFT-type wave functions, where the particle-hole picture is clear and explicit. The present work is limited to those particular ansätze, with an emphasis on connections between different visualization tools that exist in the literature.
