The CN(A2Πi) and (X Σ2+) vibrational distributions from the C+N2OCN+NO reaction at 300 K were determined in a low pressure flow reactor. From the chemiluminescence A2ΠiXΣ2+ the vibrational distribution of A2Πi was found to peak at υ′ = 1. From the laser induced fluorescence BΣ2+XΣ2+, the vibrational distribution of XΣ2+ was found to peak at υ″ = 4.

A C2H2—N2O combustion flame, stabilized at 2.8 torr with a temperature of 2500 K, gave a CN(A2Πi) vibrational distribution peaking at υ′ = 2 which can be attributed to the C+N2O reaction at 2500 K. However the CN ground state vibrational distribution was found to be relaxed.
