The larger impact of DFT-D3(BJ) for global double hybrids is beneficial for the larger dispersion contribution of the pyrene excimer, bringing these functionals closer to the reference with absolute deviations in D e ranging from 0.14 [B2GP-PLYP-D3(BJ), Figure ] to 4.21 kcal/mol (0.4 to 13% error), despite a slight tendency to overestimate for the unscaled functionals. In the description of D e , dispersion-corrected global double hybrids tend to outperform dispersion-corrected range-separated double hybrids (4 to 31%) though with overlapping error ranges. Global double hybrid well-positions (r e ) are improved with dispersion correction though overestimated in the range of 0.04-0.08 Å (1-3%) and outperformed by some range-separated double hybrids (0.3-3% error in r e ).
