(A) Species-associated difference spectra of the compartments resulting from the target analysis. The lifetimes resulting from the applied kinetic model in the absence of annihilation and fast equilibration are 2.5 ps, 28 ps, 40 ps, 360 ps, and 12 ns. (B) The concentration profiles of each of the compartments in time (linear-log scale), (C) Simultaneous fit of the fluorescence measured using Streak camera on closed PS2 cores (black line) excited with 400 nm (34) and mid-IR data (red line). The time resolution of the fluorescence experiment was ∼3.5 ps. In the emission rise, the instrument response function is included; the data were fitted with five components: 0.4 ps, 3 ps, 80 ps, 700 ps, and 6.4 ns. Note that the timescale in B and C is linear up to 30 ps and logarithmic thereafter.
