Description:
Nature Chemistry 6, 706 (2014). doi:10.1038/nchem.2005 Authors: Franklin D. Fuller, Jie Pan, Andrius Gelzinis, Vytautas Butkus, S. Seckin Senlik, Daniel E. Wilcox, Charles F. Yocum, Leonas Valkunas, Darius Abramavicius & Jennifer P. Ogilvie Charge separation in oxygenic photosynthesis occurs with high quantum efficiency and is yet to be fully understood. Using two-dimensional electronic spectroscopy, coherent dynamics have now been observed in the photosystem II reaction centre, where charge separation occurs. Supporting simulations suggest that the coherences have mixed electronic–vibrational (vibronic) nature, and may enhance the rate of charge separation. Leaf image: © Michael Wesemann/Alamy.
