WebJan 1, 2011 · The Grotthuss mechanism consists of proton jumps from a stationary oxygen atom to a neighbouring oxygen atom after it has rotated to the correct position between the two oxygen atoms. In the vehicle mechanism, protons attach to an oxygen ion and move together with this ‘vehicle’ (via translational diffusion). WebMechanizm Grotthussa - encyklopedia.biolog.pl.

Grotthuss was born in 1785 in Leipzig, Electorate of Saxony, Holy Roman Empire, during an extended stay of his parents away from their home in northern Grand Duchy of Lithuania. He showed interest in natural sciences and went to study first in Leipzig and later in Paris at the École Polytechnique. Several renowned scientists taught at the École Polytechnique at that time, including Antoine François, comte de Fourcroy, Claude Louis Berthollet and Louis Nicolas Vauquelin The Grotthuss mechanism (also known as proton jumping) is the process by which an 'excess' proton or proton defect diffuses through the hydrogen bond network of water molecules or other hydrogen-bonded liquids through the formation and concomitant cleavage of covalent bonds involving neighboring … See more The Grotthuss mechanism is now a general name for the proton-hopping mechanism.
