Why Ox Appears and Disappears in the S₃ State of Photosystem II: Insights from the Low Oxidation State Model

Chem. Commun., 2026, Accepted Manuscript DOI: 10.1039/D5CC05959C, Communication Alireza Ariafard, Matthew Longhurst, Gerhard F. Swiegers, Rob Stranger DFT calculations within the low oxidation state (LOS) framework reveal that the Ox ligand in the S₃ state of photosystem II is conditionally stabilised, appearing under Mn1–ligand restraints and vanishing...
