For RSHs, the sTDA parameterization process is slightly different. Here, α 2 and β 2 are set to 0, and a sTDA x , α 1 and β 1 are specifically fitted to reference energy databases for each density functional. In this work, we focus on the nonempirical range-separated exchange (RSX) variants of PBE, PBE0 and PBE0-1/3 (i.e., RSX-PBE, RSX-PBE0 and RSX-PBE0-1/3). Derived from the Coulomb-attenuating method (CAM), their fraction of EXX varies from 0, 1/4 and 1/3 at short-range electron-electron distance, respectively, to 100% in the long-range. We parameterize them for the sTDA framework following the procedure detailed in Ref. 59. It consists in optimizing the 3 parameters to minimize the error in computing the energy of 38 π → π ⋆ and n → π ⋆ excitations mentioned above. The list of the optimized parameters is reported in Table . The computed and reference energies are displayed in Tables S4 to S6 in Supporting Information. Like above, they show that for each density functional, the sTDA approach is less accurate by less than 0.1 eV in comparison to full TDDFT.
