FS-Study on Bacterial LH1 Complexes: Carotenoid Energy Relaxation Channels — •Peter Gaertner¹, Helmut Port¹, Marcus Branschaedel², and Robin Ghosh² — ¹3. Physikalisches Institut, Uni Stuttgart — ²Abteilung Biophysik, Biologisches Institut, Uni Stuttgart

Comperative fs-spectroscopic investigations on light-harvesting 1 (LH1) complexes from mutants of Rhodospirillum rubrum (R.r.) are reported. The carotenoid chain length effects in LH1 environment are different from carotenoids in solution. The competitive energy relaxation pathways are distinguished upon state-selective photoexcitation.
