Figure 4.

The first moment dependence on α is shown for four data sets, for each set α is increasing with an increase of intensity. The rate equation predictions for the four datasets are represented by dashed lines with colors matching the respective dataset, however, all of the models overlap due to nearly identical dependence on the parameter α. The region with approximately linear dependence of the FM on α is highlighted. The three horizontal bars in the highlighted region show the difference between the FM values of Mn³⁺ and Mn⁴⁺ oxides from the reference Mn²⁺ oxide to indicate typical FM shifts between different oxidation states of Mn ions.”
