Table 1. Kinetic Parameters and Branching Ratios of the Pfr* State Based on the Target Model from Figure 8Aa.

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.
