Figure 4

Power-induced triplet excited-state resonance Raman spectra in the v1 (A) and v4 (B) regions of the carotenoid molecules in LHCII trimers excited at 514.5 and 528.7 nm. The blue and black traces were obtained after excitation with 30 μW and 200 μW, respectively. The red traces are the difference spectra and are ascribed to the positions of the triplet states (these are magnified in the v1 region). Also shown is the power-induced triplet excited-state resonance Raman spectra in the v1 region of CP43 trimers when excited at 528.7 nm. T = 77 K.
