WebJul 18, 2013 · The textbook descriptions of the Grotthuss mechanism paint a picture of all of the protons in the ensemble diffusing with a similar mechanism. We find instead that, rather than undergoing an exclusive stepwise hopping, the proton goes through periods of bursts in activity, where it can jump 4–8 Å in distance over several water molecules on ...
