摘要：

The adsorption of D2O on Pt(111) at 20 K has been investigated by infrared reflection absorption spectroscopy (IRAS). Water was found to form as a dimer at low coverages and it grew a tetramer molecule at high coverages. The structures of the cluster water molecules on the surface were derived from the intensities and the frequencies of symmetric and asymmetric v OD stretching absorptions. The annealing at higher temperatures than 130 K was needed to form an ice bilayer island structure. (C) 1999 Elsevier Science B.V. All rights reserved.
