Excitation transfer and quenching in photosystem II, enlightened by carotenoid triplet state in leaves
{{output}}
Accumulation of carotenoid (Car) triplet states was investigated by singlet-triplet annihilation, measured as chlorophyll (Chl) fluorescence quenching in sunflower and lettuce leaves. The leaves were illuminated by Xe flashes of 4 μs length at half-height and... ...
