N2 - We report measurements of the ultraviolet absorption cross sections of 32SO2, 33SO2, and 34SO2, recorded from 30,300 to 52,500 cm-1 (330 to 190 nm) at 293 K with a resolution of 25 cm-1. The 33SO2, sample was produced by the combustion of isotopically enriched 33S while the 34SO2 and natural abundance samples were obtained from commercial manufacturers. The spectrum of the natural abundance sample is in agreement with previously published spectra. The spectra of the isotopically pure species were retrieved using the isotopic composition of the samples. The 32SO2, 33SO2, and 34SO2 absorption spectra show rich vibrational structure, and the positions and widths of the peaks change with isotopic substitution in a complex fashion. The results imply that large wavelength-dependent and broadband isotopic fractionations are associated with the UV photolysis of SO2.
