| 摘 要： | 紫外光解CHBr_3被认为是产生有着重要意义的CH 自由基的主要途径,Lin首先用闪光光解法研究了CHBr_3+O_2体系的真空紫外光解.我们用自行设计的分子光解时间分辨富里叶红外发射谱仪(FTIR-TRS),重新研究了这一体系在193nm 的光解反应,得出了一些与前人不同的结果.我们仪器的工作原理已做过详细的描述,这里在光解室里注入了混合的约5Pa 的CHBr_3(Baker 公司试剂,未进一步纯化)和230Pa 的O_2(北京氧气厂电子级高纯氧),用35mJ

| Abstract: | Photolysis of the CHBr_3+O_2 system with the 193 nm laser has been investigated by means of our UV laser photolysis time-resolved infrared spectrometer. CO(v, X~1Σ~+) was observed up to v=10 and population conversion up to v=5. The quenching constants for CO(v=1 to 10) by O_2 have also been deduced. We think that the reaction CHBr_(x)+O_2→CO(v, X~1Σ~+)+other products(x=1 or 2) plays an important role under our experimental conditions. |
