WebIn 1804, Theodore von Grotthuss proposed a mechanism for proton (H+) transport between water molecules that involves the exchange of a covalent bond between H and O with a hydrogen bond. This mechanism also supports the transport of OH-as a proton hole and is essential in explaining proton transport in intramembrane proton channels. 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 … See more 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). … See more Some evidence from theoretical calculations, supported by recent X-ray absorption spectra, has suggested an alternative … See more The Grotthuss mechanism, along with the relative lightness and small size (ionic radius) of the proton, explains the unusually high diffusion rate of the proton in an electric field, relative to that of other common cations (Table 1) whose movement is due … See more • Roberts, Sean T.; et al.
