Additional calculations using the spin-component scaled (SCS-)MP2D method are provided for comparison with the DFT results. SCS-MP2D subtracts out the uncoupled HF dispersion from MP2, replacing it with coupled Kohn-Sham dispersion. Finally, spin components of the MP2 correlation energy are empirically scaled. This approach is inspired by Heßelmann's corrected MP2 (MP2C) model, the key difference being that the SCS-MP2D correction is framed in terms of the atom-atom D3 dispersion correction, 67 rather than intermolecular perturbation theory response functions. This makes SCS-MP2D applicable to both inter-and intramolecular interactions. SCS-MP2D does not suffer from SIE, and benchmark calculations demonstrate very good performance for challenging conformational energies. SCS-MP2D results reported here were extrapolated to the complete basis set (CBS) limit based on calculations using aug-cc-pVTZ and aug-cc-pVQZ, following the procedure described in Ref. 26.
