Use of Bader’s binary AIM model gives significantly different SEDI as a function of internuclear distances than do self consistent Hirshfeld based AIM models. DAFH eigenvectors remain very similar for all AIM among the different methods. The corresponding eigenvalues are found to differ significantly although the sums of complementary eigenvalues show only relatively small changes. The choice of a binary division of molecular space into AIM domains is found to lead to extra structure in SEDI curves, but this probably has limited chemical significance.
