). The experimental data are from UV-vis spectroscopy (filled symbols) and 1H-NMR (open symbols), and are divided into three regions: (A) 51 Gy min−1 at 36 °C (solid curve), (B) 150 Gy min−1 at 40 °C (dashed curve), and (C) 250 Gy min−1 at 42 °C (dotted curve). Lines are predicted values from multiscale modelling calculations.
