Table 1. Time Constants for 1 Extracted by Global Lifetime Analysis of MA TA Spectra Pumped by 400 and 325 nm (Evolution-Associated Spectra Are Shown in Figure S5a,b)a.
| 400 nm | 325 nm | |
|---|---|---|
| τ1 | 200 fs | 170 fs |
| τ2 | 19.5 ps | 4.7 ps |
| τ3 | +∞ | +∞ |
The long-lived component τ3 stems from the 5.7 ns fluorescence lifetime of 1, which is not resolved in the TA delay time window.
