By means of fluorescence measurements singlet-singlet excitation annihilation in the antenna of Rhodospirillum rubrum chromatophores was studied at temperatures between 300 and 4 K. Two fluorescence bands had to be assumed to explain the data at 4 K. These bands (F911 and F918) are attributed to emi...
