The binding of excimers and exciplexes inherently relies on the system's excited-state properties and the dominating types of NCIs, which introduces additional complexity compared to the ground-state case. Linear-response time-dependent DFT within the adiabatic approximation (TD-DFT) has become the method of choice to treat excited-state problems. Recent advances and detailed benchmark studies on singlemolecule cases have shed light on the quality of TD-DFAs for the calculation of excitation energies. As recently summarised for readers unfamiliar with the field, lower rungs on the Jacob's Ladder of DFT should be avoided due to the emergence of artificial ghost states and large red shifts in excitation energies. Global-hybrid DFAs can be suitable for local valence excitations, subject to having the right amount of nonlocal Fock exchange (FE)-about 40% -but fail for CT and other long-range transitions. While the range-separation (RS) technique applied to the exchange part of DFAs solves the long-range problem, local valence excitations tend to be blue-shifted. Time-dependent DHDFAs depend additionally on a nonlocal, perturbative electron-correlation component that compensates for many of the systematic errors of hybrids. In fact, our group recently developed RS-DHDFAs that belong to some of the currently most robust TD-DFT methods for a variety of different local and long-range valence excitations in organic molecules. A slightly dif- ferent group of RS-DHDFAs have also proven to be very promising when used within the Tamm-Dancoff Approximation 80 (TDA-DFT). Compared to single-molecule cases, there are fewer systematic studies that explore NCIs in excited states of molecular complexes. However, it is expected that TD-DFT methods inherit the problems of the underlying ground-state DFA, such as the inability to properly describe London dispersion interactions. Additionally, the TD-DFT formalism itself carries problems that may further complicate the treatment of excited-state NCIs. In 2008, Huenerbein and Grimme presented a study of excimers and one exciplex across a very limited number of TD-DFAs. The study was unique in the sense that a London dispersion correction was rigorously applied to an excited-state study, namely the DFT-D2 correction developed in 2006. Although the dispersion coefficients used in DFT-D2 were based on ground-state polarisabilities, the combination of DFT-D2 with high-FE global-hybrid DFAs, showed a qualitatively better agreement with experimental data compared to dispersion-uncorrected TD-DFT, both for the stability of the dimers and the inter-monomer equilibrium distance. The authors' argument was that a ground-state based correction should be seen as a lower bound for the dispersion energy in an excited-state system, as C 6 coefficients are different, and most likely larger, for more polarisable excited states. Some of the subsequent TD-DFT based studies on excimer and exciplex systems either do not explore the dispersion problem of DFT or erroneously justified the use of Minnesota functionals 87 for consideration of dispersion effects, despite ground-state based studies that disprove claims they are able to treat such interactions. Some other studies recognised the dispersion problem, but for a lack of a better choice, followed Huenerbein and Grimme's recommendation to use a global-hybrid combined with DFT-D2, , while fewer applied the newer, groundstate based DFT-D3 method in its zero-damping [DFT-D3(0)] or in its Becke-Johnson-damping [DFT-D3(BJ) ] form. To our knowledge, only three studies have considered adjusting dispersion corrections for excited states. In the first, Ikabata and Nakai 107 calculated excited-state dispersion coefficients within the local-response dispersion 108,109 (LRD) model to explore the interaction energies of exciton-localised molecular complexes from the S66 110 benchmark set as well as three molecular excimers. Then, Briggs and Besley 111 empirically varied the dispersion coefficients and van der Waals radii in DFT-D2 for small model systems of ethene-argon and formaldehydemethane complexes. And finally, Johnson and co-workers calculated dispersion coefficients within the exchange-hole dipole mo-ment (XDM) model for excited states of conjugated hydrocarbons, pull-pull chromophores, and CT complexes. While these studies considered suitable model systems, only a limited selection of DFAs were applied. These three studies, among others, would allow the conclusion that state-specific dispersion corrections for excited states should be developed, but further characterisation of current methods is necessary to provide guidance towards such future developments. The present paper intends to provide such characterisation.
