The photodissociation of oxalyl chloride and 2,3 butanedione at 193nm and 248nm have been studied by Time resolved FTIR emission spectroscopy. The IR fluorescence emission was observed and the rotational and vibrational populations of the CO product were obtained. It is suggested that the photolysis mechanism is two RCO radicals formed via a fission of C-C bond, followed by a decomposition of the RCO intermediate to vibrationally excited CO( v ) and R radical.
