Comments: The absorption intensities of SO2 were measured in the wavelength region 1849-3150 Å. The pressure dependence 
of the absorption intensity was investigated at 1849, 2537, and 3131 Å. The existence of an absorption continuum commencing 
at 2280 Å has been established and attributed to the dissociation of SO2 forming SO and a ground-state oxygen atom.
