The plots for this reaction are found in Figure and the relaxation times reported in Table . For the samples with non-exponential decay curves, the non-exponential processing results are found in section S4 in the supporting information. The plots all have variable scaling to account for different amounts of signal and sample measured. This allows us to better observe low signals. As always, NMR measurements are linear and quantifiable. This illustrates the viability of the T1-T2* correlation plots for reaction monitoring. Figure indicates that the methyl groups indeed increased the intramolecular mobility and decreased the T1 to a measurable level. The main peak has a T1 of 59.2 s and a T2* of 10 µs (peak C). The T1 is still very long, but it is similar to other organic solid samples measured. For example, o-phenylenediamine also has a T1 of 38.4 s and a T2* of 4 µs (figure ).
