Fig. 4. TA spectra of the artificial system. Panels a to c correspond to the |S1〉 state lifetimes of 100, 10 and 1 ps, accordingly. All the spectra are normalized to the maximum level of the spectrum at 1 ps for the state lifetimes of 100, 10 and 1 ps, accordingly. All the spectra are normalized to the maximum level of the spectrum at 1 ps for the τS1 = 100 ps parameter set (panel a). The faint gray lines correspond to spectra separated by 1 ps time step, while the faint red lines correspond to 10 ps time step, starting from 10 ps.
