Results corresponding to atom type-based atomic polarizabilities are comparable to those obtained using a simpler assignment based solely on the element. While the MRAD decreases by including the polarization correction (from 0.173 to 0.116 and 0.113), which is reflected in the corresponding histograms being centered, the dispersion is still notable. The fraction of data points that fall within a |∆E rel | < 0.05 range is slightly increased when considering atom type based atomic polarizabilies (31.3% to 31.8%).
