Using SupraFits linear regression method with two functions, Mole Ratio plots can easily be generated. Since the typical plots exhibit the chemical shift on the x axis and the ratio on the y axis, the plots obtained using SupraFit differ from the "standard" plots. However, as the chemical shifts depends on the ratio and not vice versa, SupraFit provides only the "non-standard" way. The plot can be found in Fig. ). For each series, all possible intersections of adjacent linear functions are calculated. The result for the best fit, that fit minimising the sum over all SSE, is listed in the supporting information. The intersections of the two functions per signal ranges between 1.13 and 1.27, indicating a system that exhibits 1:2 species. This is in accordance with the stoichiometry of the original model.
