采用分步扫描时间分辨傅里叶变换红外发射光谱和G3 MP2//B3 LYP/6311 G(d,p)电子结构计算方法研究了C2 HCl 2 +O2反应的产物通道和反应机理.在红外发射光谱中观察到HCl、CO和CO2的振动激发产物,并测定了产物的振动态分布,结果表明HCl和CO是振动激发的,其初生态平均振动能估计分别为59.8和51.8 kJ/mol。结合G3 MP2//B3 LYP/6311 G(d,p)计算,对反应机理进行了表征,并提出了能量上有利的反应途径。
The product channels and mechanisms of the C2HCl2+O2 reaction are investigated by step-scan time-resolved Fourier transform infrared emission spectroscopy and the G3MP2//B3LYP/6311G(d,p) level of electronic structure calculations. Vibrationally excited products of HCl, CO, and CO2 are observed in the IR emission spectra and the product vibrational state distribution are determined which shows that HCl and CO are vibrationally excited with the nascent average vibrational energy estimated to be 59.8 and 51.8 kJ/mol respectively. In combination with the G3MP2//B3LYP/6311G(d,p) calculations, the reaction mechanisms have been characterized and the energetically favorable reaction pathways have been suggested.
