The absolute quantum efficiency of bacteriochlorophyll photooxidation in reaction centres of Rhodopseudomonas spheroides.
The widely assumed correspondence between fluorescence and photochemistry in photosynthetic systems has recently been challenged by observations on the triplet state of bacteriochlorophyll inExpand

PRIMARY REACTIONS IN BACTERIAL PHOTOSYNTHESIS—I. THE NATURE OF LIGHT‐INDUCED ABSORBANCY CHANGES IN CHROMATOPHORES; EVIDENCE FOR A SPECIAL BACTERIOCHLOROPHYLL COMPONENT
Light‐induced optical changes have been examined in chromatophores of Rhodopseudonionas spheroides (wild type and blue‐green mutants), Rhodospirillum rubrum and Chromatium. The bacteriochlorophyllExpand
