laser energy, bath gas, and bath gas pressure are altered. The products of the IRMP induced photolysis of 2-acyl-3-ethoxy-2-methyloxetane, Ox1, are primary biacetyl and ethyl vinyl ether. When the photolysis is run with the collimated beam of a CO/sub 2/ laser (1-3 J/cm/sup 2/) luminescence is observed. The intensity of the luminescence varies with the efficiency of the unimolecular decomposition of
在低压(约 100 毫托)下检测了几种氧杂环丁烷的红外多光子 (IRMP) 诱导光解,同时改变了实验变量,如激光频率、激光能量、浴气和浴气压力。IRMP 诱导 2-acyl-3-ethoxy-2-methyloxetane Ox1 光解的产物是伯联乙酰和乙基乙烯基醚。当使用 CO/sub 2/ 激光 (1-3 J/cm/sup 2/) 的准直光束进行光解时,观察到发光。发光强度随氧杂环丁烷单分子分解的效率而变化。根据 Ox1 照射后发光的光谱分布和时间行为,据信发射体是振动热的电子激发联乙酰。与 2 类似的实验,2-二甲基-3-乙氧基氧杂环丁烷明显由于激发态丙酮而产生较弱的发射。结果根据 Paterno-Buchi 反应的逆反应 - 非绝热逆光环加成进行讨论。52篇参考文献,6幅图,3张表格。
