Abstract

It is shown that CN is formed from CO in active nitrogen by reaction with an excited state of N₂, probably the ν′ = 0 level of the W³Δ_u state, and excited by energy transfer from an excited state of N₂, probably the ⁵Σ state. The

A^{3} Σ_{u}^{+}

state of N₂ is not involved in either the formation or excitation of CN. The three‐body association of C and N to form CN, although important in maintaining a fixed ratio between [C] and [CN], is unimportant in forming electronically excited CN. These statements may apply only to conditions where [Ar] ≫ [N₂] in the discharge as well as in the observation region and for small additions of CO.
