The high brightness of a synchrotron radiation source has been utilized to investigate adsorption occurring on a single crystal transition metal oxide surface with far infrared reflection absorption spectroscopy (IRAS). The adsorption of H@sub2@O, H@sub2@@super18@O and oxygen on V@sub2@O@sub3@(0001) was investigated between 154K and 224K. Infrared absorption bands at 992 cm@super-1@ and 1040cm@super-1@ are observed in the spectra above and below the desorption temperature of multilayer water, indicating the presence of a chemisorbed surface species.
