Comments: Photoabsorptioncross-sections are measured for peroxydisulfuryl difluoride (FSO3)2 and the fluorosulfate radical FSO3. 
For FSO3, the cross-sections increase from 5.51 × 10-19 cm2 at 340 nm to 4.21 × 10-18 cm2 at 450 nm.
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.
