Abstract
NCN, produced by the photolysis of cyanogen azide isolated in an Ar matrix at 14°K, has been found to react readily with F2 also present in the system, leading to the stabilization of NF2CN. The absorption patterns observed for the most prominent infrared absorptions of NF213CN and of the two singly 15N-substituted difluorocyanamides are consistent with the previous vibrational assignment. When both NCN and F atoms are present in appreciable concentration, absorptions appear at 873 and at 2068 cm−1 which may be tentatively assigned to the FNCN free radical. Upon prolonged photolysis, incompletely characterized products of more extensive fluorination reactions are observed.
