| 摘 要： | 对313nm光照射CS2－O2，CS2－空气（干）和CS2－空气（湿）三种体系的研究结果表明，CS2能吸收313nm光子达激发态CS2^#，CS2^#进一步和O2作用最终COS,SO2,CO等，从三种体系中CS2氧化反应的表观速率常数的比较可见，H2O（g)的存在将增大CS2光氧化速度。对CS2在313nm光照下的氧化反应机理进行了讨论。

| Abstract: | The photooxidation of CS 2 was studied with the radiation at 313nm with different conditions,including pure oxygen?dry air and wet air matrixes.With the irradiation of 313nm,carbon disulfide can get to electronic excitation state that has the potence to react with oxygen to produce suifur dioxide,carbonyl sulfide and carbon monoxide.By comparing the apparent rate constants of three different systems,it was conclude that water vapor has a significant effect on the photooxidation of CS 2.The mechanism of the reaction has been studied also based on these results. |
