    • To obtain this value of r, we first performed a series of calculations with a much cheaper B3LYP:PM6(r) model to calibrate the convergence of r. For r = 30 Å, both the RMS and the MAX relative conformer energy deviations between the fragmented B3LYP:PM6(3.0) and the unfragmented B3LYP methods were less than 1 kcal/mol (RMS = 0.46 kcal/mol; MAX = 0.92 kcal/mol).

    • The largest number of calculations required for a MIM(r) energy was 311, whereas for a MIM(η) energy, it was 507. The largest MP2 subcalculation for MIM(r) had 580 basis functions, whereas MIM(η) had only 402 basis functions. A more detailed comparison of the different types of cutoffs (r or η) will be the focus of future work.
