Steady-state absorption (Ab) and fluorescence (Fl) spectra of peridinin (black lines), S-1-peridinin (red lines) and S-2-peridinin (green lines) recorded in different solvents at room temperature. The spectra were normalized to each other. Asterisks indicate the (0-0) vibrational bands of the S1 → S0 fluorescence in n-hexane.
