Lendzian, F.; Willigen, H. van; Sastry, S.; Möbius, K.; Scheer, Hugo und Feick, R. (19. Juli 1985): Proton endor study of the photoexcited triplet state PT in Rps. sphaeroides R-26 photosynthetic reaction centres. In: Chemical Physics Letters, Vol. 118, Nr. 2: S. 145-150


The photoexcited triplet state PT of Rhodopseudomonas sphaeroides R-26 has been investigated by ENDOR measurements performed on frozen photosynthetic reaction centre solutions. For the first time hyperfine data could be obtained for PT. These data indicate a delocalisation of the triplet state over two bacteriochlorophyll a molecules.
