Top-down formation of ethylene from fragmentation of superhydrogenated polycyclic aromatic hydrocarbons
Top-down formation of ethylene from fragmentation of superhydrogenated polycyclic aromatic hydrocarbons
Fragmentation is an important decay mechanism for polycyclic aromatic hydrocarbons (PAHs) under harsh interstellar conditions and represents a possible formation pathway for small molecules such as H2, C2H2, C2H4. Our aim is to investigate the dissociation mechanism of superhydrogenated PAHs that undergo energetic processing and the formation pathway of small …
