Scherer, P. O. J.; Fischer, S. F.; Lancaster, C. R. D.; Fritsch, G.; Schmidt, Stefan; Arlt, Thomas; Dressler, K.; Zinth, Wolfgang (10. June 1994): Time-resolved spectroscopy of the excited electronic state of reaction centers of Rhodopseudomonas viridis. In: Chemical Physics Letters, No. 223: pp. 110-115




The spectral properties of the excited electronic state of the reaction centers of Rhodopseudomonas (Rps.) viridis are studied by dichroic transient absorption spectroscopy with sub-picosecond time resolution. The theoretical analysis of the experimental results allows the assignment of the transient absorption from two dimer bands of the special pair and show its excitonic coupling to other pigments.
