| Abstract: | The UV-absorption cross sections of CS2 are reported. The absorption spectra were measured by using a diode array spectrometer over the wavelength range of 220-380 nm at room temperature (298±3)K. The maximum absorption cross section appeared around 315 nm with the value of σ(315 nm)=7.184×10－20 cm2·molecule－1. The measured data by this study were in good agreement with that reported in the literature, and used to estimate the photolysis of the CS2 in the atmosphere. |
