[1] High-resolution, ultraviolet SO 2 photoabsorption cross section data are required for modeling density and temperature profiles of SO 2 in solar system atmospheres. We report measurements of such cross sections on SO 2 at 295 K for theB 1 B 1 -X 1 A 1 and C 1 B 2 -X 1 A 1 bands over the wavelength range 220 to 325 nm. Resolving powers of up to 550,000 were employed in order to study the congested spectrum of sharp SO 2 features in parts of this region. Our data are compared to earlier values obtained with lower resolving power.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
