The feature of the ion near 2160 which is produced by acid-base reactions in cryogenic HNCO/ samples shows a small matrix induced deuterium shift. A similar shift is found for the "XCN" band near this position produced by photolysis of CO/ ice. This agreement, together with the abundant evidence already in the literature, clearly demonstrates that the XCN feature can be assigned to .
