The formation of the chemical products produced in an
atmospheric glow discharge fed by a N2-CH4 gas mixture has been
studied using Fourier Transform InfraRed (FTIR) and Optical Emission
Spectrometry (OES). The measurements were carried out in a flowing regime at
ambient temperature and pressure with CH4 concentrations ranging from
0.5% to 2%. In the recorded emission spectra the lines of the second
positive system CN system and the first negative system of N2 were
found to be the most intensive but atomic H, H
, and C
(247 nm) lines were also observed. FTIR-measurements revealed HCN and
NH3 to be the major products of the plasma with traces of
C2H2. These same molecules have been detected in Titan's
atmosphere and the present experiments may provide some novel insights into
the chemical and physical mechanisms prevalent in Titan's atmosphere with
these smaller species believed to be the precursors of heavier organic
species in Titan's atmosphere and on its surface.
