In summary, we find no support for a universal prohibition on 6-311G-type basis sets for thermochemical DFT calculations, provided that appropriate polarization functions are included. Although basis sets such as 6-311G(d,p) do exhibit larger errors, as documented in Ref. 1, the 6-311G(2df,p) basis set affords statistical performance on par with def2-TZVP at roughly half the cost, while basis sets such as 6-311+(3df,2pd) and G3Large afford accuracy rivaling def2-QZVPD at 5-10% of the cost. Where diffuse basis functions are involved, we have clarified that numerical thresholds that are sat-isfactory for small molecules are often inappropriate for larger ones, yet robust SCF convergence is recovered using tight thresholds.
