SO₂ and CS₂ cross section data in the ultraviolet region

Abstract

Using synchrotron radiation as a continuum background, the cross sections of SO 2 in the 208‐228 and 299‐340 nm region and of CS 2 in the 318‐350 nm region have been measured with a bandwidth of 0.06 nm. It has been confirmed that the reported band positions of SO 2 in the 170‐315 nm region by Warneck et al . (J. Chem. Phys. 40 , 1132, 1964) should all be shifted by ∼ 0.3 nm toward shorter wavelengths. An important application of the present results is found in the SO 2 and CS 2 mixing ratio calculations for Venus and Io.
