Abstract
The CN stretch of the OCCN radical was observed for the first time at $2093 cm^{-1}$. The method of detection was by nanosecond Fourier-transform infrared emission spectroscopy. The radical was produced through UV photodissociation($\lambda=193$ nm) of carbonyl cyanide, $CO(CN)_{2}$ and pivaloyl cyanide, $CO(CN)(CH_{3})_{3}$ which leaves the radical with sufficient internal excitation. Infrared and near-infrared emission from all vibrationally excited species was detected. Pressure dependence, rotational band contour analysis and ab initio calculations all aided in assignment.
