The DC flowing post-discharge was used for the experimental study. The active discharge was created in a Pyrex or quartz discharge tubes with a 120 mm electrode distance at current of 200 mA and pressure of 1000 Pa. Temperature inside the decaying plasma at 77 K wall temperature was calculated of about 100 K by using the simulated nitrogen 1st positive 2-0 band spectrum. Nitrogen 1st and 2nd positive and 1st negative systems were recorded in all spectra. The bands of NO-beta system dominantly originating from vibrational level 0 were observed, too. The bands of NO-gamma system dominantly originating also from vibrational level 0 were observed when quartz tube was used. No other molecular or atomic emissions were observed. The presence of oxygen traces significantly increase concentration of nitrogen atoms and NO molecules, concentrations of the other species are quenched proportionally to the oxygen trace concentration. The effect is stronger at lower temperature.
