Ground-state dispersion corrections are often applied to excited-state studies justified by seemingly good outcomes from a few studies. However, it is reasonable to expect dispersion interactions to change upon electronic excitation 113 rendering any benefit application-dependent. Herein, we test these justifications for two schemes of additive DFT-D type dispersion corrections as applied to the excimer state without any statespecific adjustment. The DFT-D3(BJ) and DFT-D4-hereafter dubbed "D3(BJ)" and "D4"-dispersion energies were calculated for all points along the dissociation curves and added to the respective total excited-state energies. The analysis of these dispersion-corected dissociation energy curves focuses on four functionals B3LYP, CAM-B3LYP and B2PLYP and ωB2PLYP, i.e. two global functionals and their range-separated counterparts (minima given in Table ). A more generalised picture across all eight dispersion-corrected functionals will be provided in the overall statistical analysis in Section 4.4.
