Fluorescence microscopy on single light harvesting 2 complexes from photosynthetic bacterium Rhodopseudomonas Acidophila strain 10050 has been carried out. The polarization of the fluorescence emitted by individual complexes immobilized on a surface was detected as a function of time. Abrupt changes in the polarization of the emitted light of single chromophores were observed. These abrupt changes are attributed to a localization of the exciton on a small fraction of the chromophores on the closely coupled ring shaped aggregate of the complex.
