| Abstract
| - Reactions of laser-ablated cobalt atoms with CO and NO mixtures in excess argon during condensation at 7K generate a series of unsaturated cobalt carbonyl nitrosyls including Co(CO)(NO), Co(CO)[NO], OCo(NCO), CO(CO)2(NO), Co(CO)2[NO], and Co(CO)(NO)2, and the saturated Co(CO)3(NO) molecule. Theobserved infrared bands of reaction products are identified by isotopic substitution, isotopic ratios, and isotopicdistributions (13CO, 15NO, 15N18O, and mixtures). DFT/BPW91 vibrational fundamental calculations reproducedthe observed frequencies and isotopic shifts very well. The isocyanate OCo(NCO) is formed from the side-bonded Co[NO] reaction with CO, which is relevant to catalytic reduction processes.
