Temperature dependence of isotope effects on 1/T1 for isotopically-substituted tempone in glycerol and 1:1 water:glycerol. The (□) and (■) points are the H/D ratio in water glycerol and glycerol, respectively. The (△) and (▲) points are the 14N/15N ratio in water:glycerol and glycerol, respectively. Since the experimental data were recorded at different temperatures, interpolation was used to calculate 1/T1 at defined 5 K intervals and those interpolated values were used in the comparisons. Uncertainties in the ratios are about ±0.03.
