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 the 1 B 1 ‐ 1 A 1 and 1 B 2 ‐ 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.
