When clean Cu(111) was exposed to HNCO at 300 K, no adsorption occurred. When the surface was predosed with oxygen, however, HNCO adsorbed with concomitant release of water. Auger analysis of the sample showed signals of C, N and O. The ratio of the relative intensities of the N and C signals remained the same with the increase of the coverage. ELS showed losses which were not observed during the adsorption of either CO or atomic N. No HNCO was desorbed as such, and neither NCO nor (NCO)//2 was detected during the desorption. The main products were CO//2 (463 and 633 K), N//2 (793) and C//2N//2 (874 K).
