Two-dimensional Electronic Spectroscopy of Photosynthetic Light-Harvesting Complexes
Elizabeth L. Read,Gregory S. Engel,Donatas Zigmantas,Tessa R. Calhoun,Gabriela S. Schlau-Cohen,Graham R. Fleming +5 more
TL;DR: A variety of two-dimensional electronic spectroscopy experiments on natural light harvesting complexes reveal inter-chromophore coupling and monitor ultrafast dynamics, furthering understanding of the way these proteins function and the underlying design principles of photosynthesis as discussed by the authors.
Journal ArticleDOI
Phycobilisome’s Exciton Transfer Efficiency Relies on an Energetic Funnel Driven by Chromophore–Linker Protein Interactions
Siddhartha Sohoni,Lawson T. Lloyd,Andrew Hitchcock,Craig MacGregor-Chatwin,Indranil Ghosh,C. Neil Hunter,Gregory S. Engel +6 more
TL;DR: In this paper , a two-dimensional electronic spectroscopy polarization scheme that enhances energy transfer features was used to directly observe energy flow in the phycobilisome complex of Synechocystis sp.
Proceedings ArticleDOI
Probing Delocalization in Photosynthetic Antenna Complexes with Femtosecond Chiral Two-Dimensional Spectroscopy
TL;DR: In this paper, a chiral two-dimensional mapping of light harvesting complex is presented, which allows us to follow femtosecond changes in the chirality of the electronic structure, providing detailed insights into the excitation energy transfer events.
Proceedings ArticleDOI
2D Fourier Transform Electronic Spectroscopy of Photosynthetic Reaction Centers: Mapping coupling in the B band
Gregory S. Engel,Tessa R. Calhoun,Donatas Zigamantas,Tomáš Mančal,Hohjai Lee,Graham R. Fleming +5 more
TL;DR: In this article, the B800 band of the reaction center complex of Rhodobacter sphaeroides has been probed with two-dimensional Fourier transform electronic spectroscopy using 40 fs pulses and evidence for coupling within the band is presented.
