Immobility of protons in ice from 30 to 190 K
Article Abstract:
Hydronium ions transportation in ice is believed to be closely linked to transportation in water. There are claims that such tunnelling can continue even at O K in ice, but counter-claims indicated that hydronium motion energy in ice is non-zero. Soft-landing of hydronium ions on ice is used to show that ions do not appear to move at temperatures below 190K, indicating that hydronium motion is an activated process and does not occur at rates expected from the Grotthuss mechanism.
