    • The Ado TA deactivation decay in the visible region can also be fit roughly by a one-exponential function, and the 0.23 ± 0.02 ps time constant determined for the 570 nm wavelength is close to the 0.29 ± 0.04 ps value reported at this wavelength in ref 5b. We found however that the time constant obtained from the single-exponential fitting is close to the average time constant (∼0.20 ps at 570 nm) obtained from the two-exponential fitting. From this and the very similar excited-state dynamics displayed by the corresponding TA and KTRF spectra, we consider the single-exponential TA time constant being the weighted mean of the two exponential time constants determined from the KTRF dynamics (Figure 2b). We therefore think it is unlikely that one alternative excited state is responsible for the observed TA spectra, though, in some other cases, the TA and KTRF measurements may detect electronic transitions of different excited states.
