From: High-pressure pump–probe experiments reveal the mechanism of excited-state proton-coupled electron transfer and a shift from stepwise to concerted pathways

Extended Data Fig. 1: Mechanistic scheme depicting structural formulas of reaction intermediates, with their oxidation and protonation states.

Overall mechanistic scheme and overview of experimentally obtained activation and reaction volumes, respectively, for each elementary reaction step, enabling mechanistic assignments under applied experimental conditions (k5 corresponds to PT2 step in Fig. 1).
