In Section 2, we outline the theoretical underpinning of spin-component and spin-opposite scaling and how this applies to (range-separated) double hybrids for the calculation of total excited-state energies. Section 3 briefly outlines the computational details for our tested methods and the procedure for DFT-D3(BJ)/D4 damping parameter fits. Focusing on two of the same four excimer systems as in our previous study, the smallest and largest, analysis of methods without dispersion corrections is carried out in Section 4.1, and then with DFT-D3(BJ) and DFT-D4 dispersion corrections in Section 4.2. Finally, in Section 4.3 we explore the performance of each functional based on the recovery of the excimer binding averaged across all four systems.
