The photoionization and dissociative photoionization of 1,4‐di‐tert‐butyl‐1,4‐azaborinine by means of synchrotron radiation and threshold photoelectron photoion coincidence spectroscopy is reported. The ionization energy of the compound was determined to be 7.89 eV. Several low‐lying electronically excited states in the cation were identified. The various pathways for dissociative photoionization were
据报道,通过同步辐射和阈值光电子光子重合光谱法对1,4-二叔丁基-1,4-氮杂鸟嘌呤进行了光电离和离解性光电离。测定该化合物的电离能为7.89eV。阳离子中存在几个低电激发态。利用统计理论对解离光电离的各种途径进行了建模,并获得了表观能量AE 0K。逆硼氢化反应中异丁烯的损失是主要途径,该过程以反向势垒进行。在化学反应器中母体化合物的热解导致生成了几种尚未观察到的硼化合物。C 4 H的电离能从阈值光电子光谱确定了6 BN异构体1,2-和1,4-二氢-1,4-氮杂硼嘌呤和C 3 H 6 BN异构体1,2-二氢-1,3-氮杂硼烷。
