【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.更多还原
