Resonant dynamics of gas-phase electron-driven reactions: The coronene molecule as a prototype in planetary atmospheres and interstellar clouds

摘要: Abstract We present in this study multichannel scattering calculations for the interaction of low-energy electrons with a fairly large aromatic molecule, C24H12 system (coronene), that is generally considered representative medium-size polycyclic hydrocarbons (PAHs) postulated to be interstellar medium (ISM), as well diffuse and dense molecular clouds. The reaction dynamics shown undergoing several, well-marked, complex formation processes provide important precursors ensuing evolution, including either stabilization undissociated, bound negative species or fragmentation (dissociative electron attachment) paths.
