Table 1. Kinetic Parameters and Branching Ratios of the Pfr* State Based on the Target Model from Figure 8Aa.
initial occupancy (%) | apparent τ | % (Pfr* to GSI) | % (Pfr* to Lumi-Fr) | Φ (Lumi-Fr) (%) | |
---|---|---|---|---|---|
Pfr* I | 6 | 180 fs | 27 | 73 | 4.4 |
Pfr* II | 94 | 1.9 ps | 88 | 12 | 11 |
The apparent τ is the observed lifetime of the spectral species. % (Pfr* to GSI) is the branching ratio of the respective Pfr* population to GSI1, and % (Pfr* to Lumi-Fr) is the branching ratio from Pfr* to Lumi-Fr. The addition of both parameters makes up 100% for respective subpopulations. Φ (Lumi-Fr) is the final quantum yield of Lumi-Fr in reference to the total (Pfr I + Pfr II) excited Pfr molecules.
