Transient absorption dynamics of synthetic eumelanin in HPLC-grade water suspension excited at 2.254 eV and probed at: (A) 1.741 eV (ħωprobe < ħωStokes), (B) 1.823 eV (ħωStokes < ħωprobe < ħωpump), and (C) 2.460 eV (ħωpump < ħωprobe < ħωanti–Stokes). The red lines are the result of a fitting procedure using a bi-exponential decay function; the blue line is the measured IRF.
