| 摘 要： | 用时间分辨富里叶红外发射谱仪（ＴＲ－ＦＴＩＲＳ）研究了ＣＨ２（Ｘ＾３Ｂ１）自由基与Ｏ２反应的通道及产物的振动动态布居，基电子态自由基ＣＨ２（Ｘ＾３Ｂ１）由３５１ｎｍ紫外激光光解ＣＨ２ＣＯ生成，观测到振动发态反应产物ＣＯ（ｖ≤１０），ＣＯ２（ｖ３≤７）ＯＨ（Ｈ２Ｏ）和Ｈ２ＣＯ的红外发射，证实存在生成Ｈ２ＣＯ的通道，由光谱拟合得到不同时刻ＣＯ（ｖ）和ＣＯ２（ｖ３）的相对振动布居，发现ｖ＝４能级的布居数

| Abstract: | The reaction of methylene radical CH2(X3B1)with molecular oxygen was investigated with Time-Resolved Fourier Transform Infrared spectrometer(TR-FTIRS). Pure CH2(X3B1)radicals were produced by UV photolysis of ketene at 351nm. Vibrationally excited products OH(or H2O) and H2CO were observed in the infrared emission spectra. The H2CO channel was verified as a product of elementary reaction. The nascent vibrational distribution of CO and CO2 were obtained. The most populated vibrational level was v=4 for both the CO and CO2. |
