Abstract

The observation of infrared emission of CO with time-resolve Fourier transform spectroscopy (TR-FTS) upon photolysis of (ClCO)2 at 193 nm was presented. A four-body mechanism of decomposition was proposed to account for the energy balance. The rotational distribution of CO was found to be Boltzmann type, and average rotational and vibrational energies were recorded as 23±3 and 26±4 kJ mol-1, respectively. No emission of ClCO near 1880 cm-1 was observed, which indicated that surviving ClCO had little vibrational excitation in the C-O stretching mode.
