Photo-conversion of chlorohpylls in higher-plant CP43 characterized by persistent spectral hole burning at 1.7 K
The chlorophyll-protein complex CP43 is a proximal-antenna subunit important for excitation energy transfer from peripheral light-harvesting antenna to the Photosystem II (PSII) reaction centre. We report persistent spectral hole burning at 1.7K in the Qy(0,0) origin and Qy(1,0) vibrational satellite bands of chlorophyll a (chl a) in CP43 isolated from higher plants. The isolated CP43 is known to possess two quasi-degenerate 'red' trap states. We find persistent hole burning in the primary trap...[Show more]
