A negligible impact of dispersion corrections for unscaled range-separated double hybrids ωB2PLYP and ωB2GP-PLYP has been previously noted for excimer binding and in ground-state benchmarking on the GMTKN55 database, both overall and specifically in the NCI category. Due to the inverse relationship between D e and the impact of the dispersion corrections, underbinding errors (more common for spin-scaled variants) are reduced whereas overbinding errors remain the same as in the dispersion-uncorrected functional. While this behaviour is present for RSX-QIDH-based functionals [Figure ], it is more apparent for the BLYPbased functionals [Figure ]. As mentioned in Section 3.2, we reoptimised the DFT-D3(BJ)/D4 damping parameters for these functionals with a larger fit set, but it seems the nature of the fit set does not impact the observed negligible impact DFT-D type dispersion corrections seem to have on these functionals.
