Graphical Abstract

Sequences of high resolution low-temperature emission spectra from individual light-harvesting 2 (LH2) complexes from Rhodopseudomonas acidophila reveal a much larger variety of the emission profiles than previously observed. The results provide direct evidence for substantial variations in electron–phonon coupling and concomitantly of exciton (de)localization within single pigment-protein complexes.
