摘要: Abstract The absorption cross sections, as important spectroscopic data, can be used for the identification and quantitative measurement of components. However, in view that carbon monosulfide (CS) is unstable highly reactive, it difficult to measure sections CS. Therefore, a method measuring CS based on dynamic equilibrium between disulfide (CS2) photolysis CS2 proposed paper, are obtained first time. Firstly, evaluating concentrations introduced, calculation formula given. Secondly, converted by increasing intensity incident light. Factors affecting conversion efficiency, such flow rate light, studied. Next, according relationship CS, concentration has been change concentration. Finally, (0.29 ± 0.01) × 10−16 cm2/molecule (2.15 ± 0.04) × 10−16 cm2/molecule provided at wavelengths 250.88 nm 257.60 nm, respectively.
