Spin scaling generally reduced excimer binding strength compared to an unscaled method with an impact on overall errors that was functional and system dependent. The relative binding strength for each base functional follows the trend unscaled > SCS > SOS, with the exception of SCS-RSX-QIDH which predicts a stronger binding than RSX-QIDH due to its large same-spin scaling component. Given the prevalence of underbinding exhibited by TD-DFT methods, double hybrids included, spin scaling tends to yield larger errors than unscaled methods. However, where the base functional overestimates-drastically in the case of ωPBEPP86-spinscaled methods can be closer to the reference than unscaled methods. Despite the varied impact of spin scaling, the smallest average errors, and most promising functionals, belonged to the spin-scaled functionals: SCS-RSX-QIDH-D3(BJ), SCSand SOS-ωPBEPP86-D3(BJ).
