High-resolution photoabsorption cross-section measurements of SO2 at 198 K from 213 to 325 nm

Research output: Contribution to journalArticle

Abstract

SO2 plays an important role in the atmospheric chemistry of the Earth, Venus, and Io. This paper presents photoabsorption cross sections of SO2 from 213 to 325 nm at 198 K, encompassing the (C) over tilde B-1(2) - (X) over tilde (1)A(1) and (B) over tilde B-1(1) - (X) over tilde (1)A(1) electronic bands. These measurements are part of a series of measurements over the 160 to 300 K temperature range between 190 and 325 nm. The cross sections have been measured at high resolution (lambda/Delta lambda approximate to 450,000) using Fourier transform spectrometry and are compared to other high-resolution measurements in the literature.
