Comments: Photoabsorptioncross-sections are measured for peroxydisulfuryl difluoride (FSO3)2 and the fluorosulfate radical FSO3. 
For (FSO3)2, the cross-sections measured at 298 K decline smoothly from 7.43 × 10-18 cm2 at 180 nm to 1.27 × 10-21 cm2 at 340 nm. 
At wavelengths between 340 and 450 nm, temperature-dependent measurements yield both dimer and radical cross-sections.
