Notes:
Cl atoms and CO molecules were trapped in a solid Ar matrix at 16 K. The formation of ClCO was followed via its IR spectrum. The vibrational frequencies of 35Cl12C16O were observed at 1876.7 , 570.1, and 334.6 cm−1. Experiments with different CO isotopomers were performed in order to confirm the assignment of the absorptions and to characterize the force field. The results extend and correct earlier data [M. E. Jacox and D. E. Milligan, J. Chem. Phys. 43, 866 (1965)]. With the help of quantum chemical calculations (UHF, MP2), the optimized ClCO bond angle was obtained to be 129.2°. The computed bond lengths were determined to be 1.159 A(ring) for C–O and 1.807 A(ring) for C–Cl. Based on force constant calculations, the C–Cl bond in ClCO was found to be extremely weak compared to that in Cl2CO.
