Low-temperature polarization dependent fluorescence-excitation spectra and fluorescence emission spectra are recorded from the same individual light harvesting 2 complexes from Rps. acidophila strain 10050. Combining fluorescence excitation and emission spectroscopy provides detailed information about the exciton band structure and the electron phonon coupling within these complexes. We have been able to identify the emission from the lowest exciton state (k=0).
