Gas-Phase Positive Ion Insights during Laboratory EUV Irradiation of Titan's Relevant Gas Mixtures
Abstract
In the atmosphere of Saturn's moon Titan, the chemical growth is believed to occur through an efficient chemical coupling between radicals and reac-tive charged species. However, the role of positively charged particles in haze formation chemistry is far from being understood. Here, we present a mass spec-trometry investigation with a relatively low pressure interface to chemically characterize the positive ions formed in the pre-haze formation phase starting from the EUV photolysis of N2 /CH4 gas mixtures.
