Abstract

We show that H/D exchange between H₂O and D₂O in ultrathin ice films adsorbed on Cu(100) does not occur through autoionization at temperatures below 140K. The exchange is, however, facile if a proton deficiency is induced in the ice films by having small amounts of OH preadsorbed on the copper surface. The system was studied using surface infrared vibrational spectroscopy with the aid of density functional theory calculations.
