We find that molecular polarizabilities computed from both element-based and Sage LJ-typed atomic polarizabilities (Equation ) agree well with those derived from experimental indices of refraction, as shown in Figure . It is worth noting that, although the element-typed polarizabilities include four types, the minimalist element-typed polarizabilities transfer well to molecules with diverse chemical environments that are not included in the training data, such as nitriles and alkynes. The chemical structures of molecules with available experimental measurements are presented in Figure . These results suggest that our atomic polarizabilities based on induced gas-phase QM ESPs retain their broader physical meaning and can be valid for use in molecular simulations.
