Retrospective Theses and Dissertations

The excited state structure, early time energy and electron transfer dynamics for bacterial photosynthetic reaction centers of Rhodoseudomonas viridis, Rhodobacter sphaeroides and green plant photosynthetic reaction center of Photosystem II (PS II) have been determined by hole burning spectroscopy. Transient hole burned spectra of the bacterial reaction centers reveal a special pair Franck-Condon marker mode progression with a superimposed zero phonon hole. Such progression is found to be absent in green plant Photosystem II which raises the question of structural similarities between the PS II and bacterial reaction centers. The excited state decay times are obtained for all systems and ...
