Quantitative optical spectroscopy measurements of the emission spectra of the N 2 + ( B 2 ∑ u ,)ν′→ X 2 ∑ g ν″ transition (first negative system) in an Ar‐N 2 microwave discharge at atmospheric pressure have allowed determination of the rate coefficient of the production of N 2 +molecules in the B 2 ∑ u , state with vibrational level ν′ = 0. The N 2 + ( B 2 ∑ u , ν′) molecules are produced by the reactionin a surface‐wave‐induced microwave discharge (2450 MHz) sustained in an open‐ended dielectric tube. The rate coefficient K ν′,ν″ ν( T ) has been obtained for ν′ν″ = 0 for different gas temperatures by varying the incident microwave power. The K 00 ( T ) values are between 7.10 −10 and 4.10 −10 cm 3 s −1 for the temperature range 2500 to 3450K.
