Webthrough water bridges and suggested that proton transfer occurs by a sequential Grotthuss-type hopping mechanism through the H-bond network of the solvent. Solvent structures near mediating water molecules must play an important role in the dynamics of direct proton relay. It has recently been shown that when the end groups have WebIn 1804, Theodor von Grotthuss in 1804 proposed a hopping mechanism for proton (H+) transfer in chains of hydrogen-bonded water. This transfer involves the exchange of the …
The Grotthuss mechanism is now a general name for the proton-hopping mechanism. In liquid water the solvation of the excess proton is idealized by two forms: the H9O4 (Eigen cation) or H5O2 (Zundel cation).
