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 .
