For the solvent model we use the "conductor-like" (C-)PCM, the switching/Gaussian (SwiG) method for surface discretization, and a van der Waals cavity to define the interface with the continuum. The cavity is constructed using Bondi's atomic radii (as modified in Ref. 37), scaled by a factor of 1.2. Atomic spheres were discretized using 194 Lebedev grid points per sphere.
