mainly generated the aniline cation (PhNH2+), anilino (PhNH) and phenyl (Ph) radicals, and phenylnitrene (PhN). Further irradiation of the electron-bombarded matrix sample at 365 nm depleted PhNH2+ and PhN, and resulted in the formation of PhNH2, PhNH, and Ph. In separate experiments, irradiation of the PhNH2/Ar matrix samples at 265 or 160 nm mainly generated PhNH and Ph radicals, but without the formation
Ar基体中苯胺(PhNH 2 )的电子轰击主要产生苯胺阳离子(PhNH 2 + )、苯胺基(PhNH)和苯基(Ph)自由基以及苯氮烯(PhN)。在 365 nm 处进一步照射电子轰击的基质样品会耗尽 PhNH 2 +和 PhN,并导致形成 PhNH 2、PhNH 和 Ph。在单独的实验中,在 265 或 160 下照射 PhNH 2 /Ar 基质样品nm主要产生PhNH和Ph自由基,但没有形成PhNH 2 +和PhN。根据观察到的光化学行为、量子化学预测的每个物种的谐波振动波数,以及之前光解研究中报道的信息,我们明确地表征了芳香族物种的红外特征。PhNH的振动基础信息是新的,并讨论了形成机制。
