Overall, it turned out to be challenging to obtain a good description of both D e and r e with hybrid functionals, whereas double hybrids provided a more robust picture. High admixtures of Fock exchange in global hybrids usually led to smaller dissociation energies or even repulsive curves. Dispersion-uncorrected global hybrids with 50 % or less Fock exchange, range-separated hybrids, as well as global and range-separated double hybrids, all gave curves with distinct minima, with the latter functional type giving the best curves, most likely due to a better description of charge-transfer and exciton coupling. That being said, all dispersion-uncorrected TD-DFT methods produced large errors that increased considerably with system size. For the smallest system, the benzene excimer, dispersion-uncorrected methods see the best results from range-separated double hybrids, approaching the accuracy of SCS-CC2/CBS (3,4) quality. However, for larger systems there was greater disparity between even the most accurate TD-DFT methods and the reference. D e values were usually underestimated and r e values overestimated, which points to missing dispersion interactions as the likely reason.
