    • An alternative explanation for the fast component of 1BpCMe biexponential decay at 360 nm could be the vibrational cooling of the ground-state BDE. This requires that the excited state of BDE regenerates its ground state with excess vibrational energy via an ultrafast internal conversion. As shown in Figure S8, the red edge of the BDE ground state UV spectrum is 360 nm; however, in the case of BDM, the red edge of its UV spectrum is blue-shifted to 345 nm. This could account for the absence of biexponential decay feature in the decay of 1BpCH at 360 nm. However, usually the quantum yield of diazo compounds is close to unity. We conclude that the explanation of hot ground-state BDE might account for the data to some extent, but it is not the main reason
