F2Δr−A2Πi band system of CN

Chemiluminescent and other processes leading to the excitation of cyanogen

“…This view has also been supported by Meyer and Setser.179 However, N2(A32U+) might be a source for production of N2t(X12g+)132 and may be responsible for the complicated pressure dependence; i.e., they suggest N + N2(A3Lu+) -N^X^) + N (14) N27 + CN -* CN*(B22+) + N2(X) (15) Young and Morrow129 have studied CN emission from an active nitrogen flame of CO. Their results appear to indicate the noninvolvement of N2(A32U+) and do not substantiate reaction 18 in the formation or excitation of CN. They favor the following reactions: N2*(W3AU) + CO -*• CN + NO (16) N2**(52) + CN -N2 + CN* (17) similar to eq 11. However, it is possible that these suggestions are valid in a limited way for their system alone.…”
