The reaction of CO with NH{sub 3} over preoxidized Rh/SiO{sub 2} has been studied by infrared spectroscopy to detect surface intermediates. Two of the surface species having infrared bands at 2172 and 2225 cm{sup {minus}1} have been identified as RhNCO and RhOCN, respectively. This is likely the first observation of these two surface species simultaneously on a supported transition-metal catalyst. High-quality ab initio computations have been employed to aid in the band assignments.
