Optical Emission Spectroscopy of Atmospheric Glow Discharge Generated in Nitrogen-Methane Gaseous Mixtures

Popis výsledku v původním jazyce

This work extends our previous investigation of nitrogen-methane (N2-CH4) atmospheric glow discharge for simulation chemical processes in Titan’s or early Earth prebiotic atmospheres. Experiments are focused on water (H2O) addition to the atmospheric glow discharge fed by N2-CH4 mixture and diagnostic of this discharge by optical emission spectroscopic (OES). The electrode system used the standard configuration of the gliding arc discharge but due to the low applied power as well as low gas velocity the discharge is not moving along the electrodes. The discharge was operated at an applied voltage of 400 V and discharge current in range 15 to 40 mA in pure nitrogen enriched by 1-5 % of CH4 (both gases having quoted purity of 99.995 %) with admixture of 2 % of H2O at the total flow rate of 100 sccm. The spectra belonging to various bands of CN violet and C2 spectral systems were recorded as well as spectral bands of OH and very weak NH bands. Also the 2nd positive and 1st negative nitrogen spectral syst
