Journal ArticleDOI
Molecular orbital investigation of dimer formations of bacteriochlorophyll a. Model configurations for the primary donor of photosynthesis
TL;DR: In this paper, three stable dimer configurations of bacteriochlorophyll a are predicted by a selfconsistent field molecular orbital calculation (all valence electrons, restricted Hartree-Fock, INDO-parametrization, perturbational treatment of spin polarization) including geometry optimization by energy minimization.
Journal ArticleDOI
ESR, ENDOR and TRIPLE resonance studies of the primary donor radical cation P960+• in the photosynthetic bacterium Rhodopseudomonas viridis
Friedhelm Lendzian,W. Lubitz,Hugo Scheer,Arnold J. Hoff,Martin Plato,E. Tränkle,Klaus Möbius +6 more
TL;DR: In this article, the light-induced radical cation of the primary electron donor P960+• in photosynthetic reaction centers from Rhodopseudomonas viridis has been investigated by ESR, ENDOR and TRIPLE techniques.
Journal ArticleDOI
Endor and triple resonance in solutions of the chlorophyll a and bis(chlorophyll)cyclophane radical cations
TL;DR: In this article, the hyperiine coupling constants (hfcs) of chlorophyll a (Chl a) and bis (chlorophyll )cyclophane (BCP) were compared with the results of molecular orbital calculations and the localization of the unpaired electron on one macrocycle of BCP + was deduced.
Book ChapterDOI
Molecular Orbital Studies on the Primary Donor P960 in Reaction Centers of Rps. viridis
TL;DR: In this paper, the relevance of the dimeric nature of the primary donor P for the fast electron transfer step from the first excited singlet state 1P*H to the charge separated state P+H−, where H stands for the intermediate acceptor bacteriopheophytin, was investigated.
Journal ArticleDOI
The radical cation of bacteriochlorophyll b. A liquid-phase endor and triple resonance study
TL;DR: In this paper, the radical cation of bacterioehlorophyll b (BChl b) was investigated by endor and triple resonance in liquid solution, and the experimental hyperfine coupling constants, ten proton and three nitrogen couplings, were compared with the predictions from advanced molecular-orbital calculations (RHF INDO/SP).
