Glow discharge formation of high molecular products in prebiotic atmospheres: PTR-TOF analyzis

Glow discharge formation of high molecular products in prebiotic atmospheres: PTR-TOF analyzis

Abstract

Chemical processes initiated by electrical discharges in prebiotic atmospheres like at Titan became a hot topic during the last decade because of extensive discovering of exo-planets. The presented contribution gives the first PTR-TOF measurements of the main compounds formed in the glow discharge in nitrogen-methane gaseous mixture with oxygen traces at temperature of 77 K and atmospheric pressure. The life precursor molecules like formamide were observed in significant amount.
