Integrated target model for both PP experiments. P_r 1–5 reflect subpopulations in thermal equilibrium, where P_r 1 and 2 are red-shifted subpopulations and P_r 3–5 are blue-shifted subpopulations. The relative amplitude of initially excited subpopulations under different experimental conditions is indicated. Parameters for 8, 25, and 40 °C are colored blue, green, and red, respectively. DEWI-PP was performed at 25 °C, and occupancy parameters are color-coded as gray and black for 600 and 670 nm excitation, respectively.
