Production of OCCN radicals by photodissociation of carbonyl cyanide CO(CN)2 at 193 nm

The photodissociation of CO(CN)2 was studied at 193 nm using photofragment translational energy spectroscopy. We measured the time of flight distributions and anisotropies of the fragments CN, CO and OCCN. The decay to CN and OCCN radicals was found to be the dominant process. About ≤25% of the OCCN fragments possess sufficient internal energy to undergo secondary dissociation to CO+CN during the flight from the reaction zone to the detector. None of the photoproduct distributions exhibit a fragment recoil anisotropy.
