Reaction between Hydrocyanic Acid and O(1D2) or O(3P) Oxygen Atoms in Low-Temperature Matrices

Article abstract of DOI:10.1021/j100345a044

The reactions of hydrocyanic acid with both excited and ground-state oxygen atoms have been examined in low-temperature matrices.The major products of HCN + O(¹D₂) reaction were isocyanic acid (HNCO) and cyanic acid (HOCN), confirming predictions of the intermediacy of HNCO and oxazirine on the pathway to the final products seen in the gas-phase reaction.In contrast, no evidence was found for reaction between HCN and O(³P) atoms in the matrix.
