Fig. 4: Ultrafast vibrational fingerprinting of DOPA melanin.
From: Probing the heterogeneous structure of eumelanin using ultrafast vibrational fingerprinting
Time-resolved vibrational spectra (TRIR) are shown at 1 ps after photoexcitation at the wavelengths indicated on the left. Spectra are normalized for clarity. Vertical dotted lines indicate ground state vibrational peak positions. The electronic (UV-vis) and vibrational (FTIR) absorption spectra of DOPA melanin are shown on the left and top, respectively, with axes that are linear in absorbance.
