Abstract The Photosystem I (PSI) reaction center in cyanobacteria is comprised of~ 96
chlorophyll (Chl) molecules, including six specialized Chl molecules denoted Chl1A/Chl1B …

Abstract 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 …

The ultrafast primary charge separation in Photosystem I (PS I) excited by femtosecond
pulses centered at 720 and 760 nm was studied by pump-to-probe laser spectroscopy. The …

Abstract In Photosystem I (PS I), the role of the accessory chlorophyll (Chl) molecules, Chl
