Original Abstract

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 (N_2 (B) -> (A)) 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.
