Abstract
The coadsorption of D2O and Na on the MgO(100)/Mo(100) surface has bee n studied by metastable impact electron spectroscopy and ultraviolet p hotoelectron spectroscopy (He I). The initial layer of D2O adsorbed on the MgO(100) surface at 100 K ''wets'' the surface. For multilayer ad sorption, the outermost water molecules exhibit an electronic structur e which is very similar to gas phase water. Na dosed onto a D2O-precov ered MgO surface leads to the formation of a hydroxide species, most l ikely NaOH. This hydroxide species is stable to 530 K. (C) 1998 Americ an Vacuum Society.
