To test the integrity of the GFN2/D4 polarizability results for the 73 member "wide range" benchmark set, we ran single point DFT polarizability calculations using the !B97X functional and the cc-pVTZ basis set. This functional was chosen because it allowed us to compare the DFT results for the "wide range" set to the previously computed results for the PubChemQC subset, since the former was performed in ORCA 4.0.0.2, which does not have an option for the exact dispersion-corrected functional used in the latter's calculations in Gaussian 09. This basis set was chosen because it was the largest basis set that we were able to reach convergence with for all species in the "wide range" set in a reasonable amount of computation time.
