In line with our previous study, the TD-DFT description of excimer binding was analysed via dissociation curves in comparison to a reasonably accurate wavefunction reference of SCS-CC2/CBS(3,4) quality. Our main goal was to assess how spin scaling, range separation and dispersion corrections impact the description of excimer binding across different underlying double hybrid functional expressions. Our analysis focused on the minima of dissociation curves (excited-state interaction energy curves) characterised by two-quantities, namely the dissociation energies (D e ) and equilibrium distances (r e ). Before these spin-scaled double hybrids could be used to generate excited-state interaction energies, we first defined the spin-scaling parameters for the MP2 ground state missing from their initial implementation. We defined the SCS/SOS-MP2 ground-state scaling parameters for each functional as the indirect scaling parameters from the SCS/SOS-CIS(D) component optimised for excitation energies, as theoretically justified in Section 2. We also optimised the damping parameters for ground-state DFT-D3(BJ) and -D4 dispersion corrections.
