Since no single charge partitioning scheme is expected to be ideal for all applications, we also compared the effect of different charge partitioning schemes for a given DFA. As shown in Figure , the differences between Bader, 64,98 DDEC6, and Charge Model 5 (CM5) 100 partial atomic charges (as computed with the PBE functional) tend to be far larger than any differences observed when changing the DFA, similar to what has been observed for several inorganic solids. 101 This is especially the case when directly comparing the Bader and DDEC6 methods. As one example of many, large deviations are often observed for the S and P atoms of SO 4 2-and PO 4 2-groups, which have partial atomic charges upwards of ~2.4 charge units higher with the Bader method than the DDEC6 method. Additionally, there can be qualitative differences between Bader and DDEC6 charges, such as atoms that have a partial positive charge with the Bader method but a partial negative charge with the DDEC6 method. While there are also clear differences between the DDEC6 and CM5 methods (Figure ), the agreement between these two charge partitioning approaches is generally greater than that between DDEC6 and Bader. For applications involving systems quite different from those in available benchmarks, it might be advisable to compare multiple partial charge schemes and further investigate any substantial differences. 102
