Inducing H/D Exchange in Ultrathin Ice Films by Proton Deficiency

Blomquist, Jakob LU ; Andersson, M. P. and Uvdal, Per LU (2011) In Physical Review Letters 107(21).
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 140 K. 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.
