However, their formation mechanisms in combustion and interstellar environments are not fully understood. The production of tricyclic PAHs and, in particular, the conversion of a PAH containing a five-membered ring to one with a six-membered ring are of interest to explain PAH abundances in combustion processes. In the present work, resonant ionization mass spectrometry in conjunction with isotopic labeling
多环芳烃 (PAH) 是形成烟灰颗粒和星际颗粒的中间体。然而,它们在燃烧和星际环境中的形成机制尚不完全清楚。三环多环芳烃的产生,特别是含有五元环的多环芳烃转化为含有六元环的多环芳烃,对于解释燃烧过程中多环芳烃的丰度很有意义。在目前的工作中,共振电离质谱与同位素标记相结合,用于研究在放电过程中苊和甲烷形成的苯环自由基。我们表明,在这种环境中,CH 环加成机制将五元环转化为六元环。
