Proton Transport of Protonic Charge Carriers in Homogeneous Media

Long-range Proton Transport of Protonic Charge Carriers in Homogeneous Media 

Such simple concepts did not include any chemical or structural details other than the chemical nature of the proton donor and acceptor, and the donor / acceptor separation. Also the dynamics of the proton environment was either reduced to the variations of the donor / acceptor separation [19-21] or described qualitatively as being solid-like or liquid-like [22]. 

However it turned out that the structural, chemical and dynamical details are essential for complex descriptions of long-range proton transport. These parameters appear to be distinctly different for different families of compounds, preventing proton conduction processes from being described by a single model or concept as is the case for electron transfer reactions in solutions (described within Marcus theory [23]) or hydrogen diffusion in metals (incoherent phonon assisted tunneling [24]).
