Résumé

Organic aerosols formed in Titan's upper atmosphere are surrounded by very reactive plasma species. The present work aims to study the potential interactions between aerosols and plasma species. The exposure of aerosols to plasma is simulated in a cold plasma reactor. IR transmission spectroscopy gives clues about the chemical modifications of the aerosols. Mass spectrometry simultaneously measures the neutral species and positive ions in the gas phase. We observe the formation of HCN and carbocations while ammonia density is decreased by the addition of organic aerosols in the N2-H2 plasma.
