Our findings are in good agreement with the reaction mechanism proposed in the transient absorption study, except for the structural assignments of the early kinetics. Considering that TRXSS is sensitive only to the processes accompanying structural change, the intersystem crossing processes on ∼500 fs and 13 ns timescales, which were not observed in the TRXSS measurement, are likely to involve no structural change.
