The method's underestimation of polarizability values, which systematically grows as polarizability increases, indicates that the application of a quadratic scaling correction factor could provide a relatively simple solution to drastically improve the accuracy of large polarizability calculations. The presence of three significant outliers in the GFN2/D4 comparison data, all containing similar sulfur motifs, suggests the need to examine GFN2/D4 parameterization for such chemical structures. Beyond increasing GFN2/D4 usefulness for e cient polarizability calculations for large polarizability molecular screening applications, these improvements would notably also improve the accuracy of the D4 dispersion method for large ⇡-conjugated species. We also note that the semi-empirical additive model for GFN2/D4 remains more accurate than calculating polarizabilities using the related sTDA-xTB model.
