Theory 03/Molecular & anomalous/Proton transport
Protons Move Faster Than Diffusion
The claim
Proton mobility exceeds ordinary diffusion because the ratio of Grotthuss hopping rate to molecular reorientation rate is large, so protons move through the network rather than with it.
01Mechanism
Charge transfers along hydrogen bonds while the network reorganises more slowly; the ratio sets the enhancement.
02Prediction
Mobility should fall as reorientation accelerates.
03Refutation
Mobility tracking hydrodynamic radius would remove hopping.
