Fig. 3: Chirp-corrected transient absorption spectra as a function of time (ps) and wavelength (nm) for all six molecules under study in hexane upon 267 nm excitation.

Note the mixed linear-logarithmic scaling of the pump–probe time-delay axis. For clarity, the plots only include a subgroup of the complete pump–probe delay dataset (individual plotted spectra are spaced by 200 fs in the linear region and the logarithmic region shows every second time-delay sampled).
