Kinetic scheme to describe the experiments in which P (880 nm) and B (796 nm) are excited. The concentration profiles of B* (dashed line), P* (solid line), P⁺B_A⁻ (crosses), and P⁺H_A⁻ (dotted line) were calculated according to the depicted kinetic scheme for P (A) and B (B) excitation by using lifetimes of 360 fs for B* → P⁺B_A⁻, 360 fs for B* → P*, 1.7 ps for P* → P⁺B_A⁻, 0.85 ps for P⁺B_A⁻ → P⁺H_A⁻, and 80 ps for the state P⁺H_A⁻. At time zero the population was considered to be 100% B* and 100% P* for B and P excitation, respectively.
