用红外反射吸收光谱（IRAS）研究了25 K时水分子在Cu（111）表面的吸附.在Cu（111）表面上观察到了四个特征吸收带，它们分别是二聚体和六聚体水分子团簇的OD伸缩。在M（111）（M = Cu，Ni，Pt）和Ru（001）表面上观察到的关键OD伸缩带的出现表明，在25K下，水的二聚体和六聚体团簇主要共吸附在这些表面上. (c)2005 Elsevier B.V.保留所有权利。
The adsorption of water molecule on a Cu(1 1 1) surface at 25 K was studied by infrared reflection absorption spectroscopy (IRAS). The four characteristic absorption bands in a v(OD) stretching region were observed on Cu(1 1 1) surface and assigned to be OD stretchings from dimer and hexamer water cluster molecules. The appearances of the key OD stretching bands observed on M(1 1 1) (M = Cu, Ni, Pt) and Ru(0 0 1) surfaces indicate that water dimer and hexamer clusters are coadsorbed dominantly on those surfaces at 25 K.
