| Description | In this work the reaction kinetics in argon flowing afterglow with nitrogen addition was studied by optical emission spectroscopy. Kinetic model showed that C~$^{3}\Pi_{u}$ state of molecular nitrogen, which is the upper state of SPS emission, is produced by excitation transfer from argon metastables to nitrogen molecules. However, the argon metastables are also produced at Ar$_2^+$ ion recombination with electrons and this limits the decay of argon metastable concentration and it results in very slow decay of second positive system intensity. |
