    Revealing core-valence interactions in solution with femtosecond X-ray pump X-ray probe spectroscopy

    Femtosecond pump-probe spectroscopy using ultrafast optical and infrared pulses has become an essential tool to discover and understand complex electronic and structural dynamics in solvated molecular, biologi...

    Structural evidence for intermediates during O2 formation in photosystem II

    In natural photosynthesis, the light-driven splitting of water into electrons, protons and molecular oxygen forms the first step of the solar-to-chemical energy conversion process. The reaction takes place in ...

    Structural dynamics in the water and proton channels of photosystem II during the S2 to S3 transition

    Light-driven oxidation of water to molecular oxygen is catalyzed by the oxygen-evolving complex (OEC) in Photosystem II (PS II). This multi-electron, multi-proton catalysis requires the transport of two water ...

    Room temperature XFEL crystallography reveals asymmetry in the vicinity of the two phylloquinones in photosystem I

    Photosystem I (PS I) has a symmetric structure with two highly similar branches of pigments at the center that are involved in electron transfer, but shows very different efficiency along the two branches. We ...
