The CN (A 2Πi) and (X Σ2+) vibrational distributions from the C+N2O→CN+NO reaction at 300 K were determined in a low pressure flow reactor. From the chemiluminescence
A 2Πi→X Σ2+ the vibrational distribution of A 2Πi was found to peak at υ′ = 1. From the laser induced fluorescence
B Σ2+→X Σ2+, the vibrational distribution of X Σ2+ 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 (A 2Πi) 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.
