matrices by laser UV photolysis of 1H-phenalene, and was identified by recording laser induced fluorescence and IR spectra. Theoretical computations predict that the H atom addition to phenalenyl radical is barrierless, while the H atom abstraction from 1H-phenalene has only a small barrier. Upon annealing the Xe matrix after the photolysis, the radical and the H atom recombine, while H atom abstraction
苯并噻吩基自由基是通过1H-苯酚的激光UV光解在惰性基质中原位生成的,并通过记录激光诱导的荧光和IR光谱进行鉴定。理论计算预测,苯并菲基中的H原子无障碍,而1H-苯并菲中的H原子仅具有较小的势垒。在光解后对Xe基质进行退火后,自由基和H原子重新结合,而从1H-菲烯中提取H原子则可能解释了其他光谱变化。这些结果表明,菲烯基/ 1H-菲系统可以是形成星际H 2的非常有效的催化剂。
