Comments: The UV absorption cross sections for gas phase pernitric acid (HO2NO2) were measured between 190 and 330 nm 
at 298 K and 1 atm total pressure. The HO2NO2 cross sections ranged from approximately 10-17 cm2 molecule-1 at 190 nm to 
about 10-21 cm2 molecule-1 at 330 nm. The experimental uncertainty (one standard deviation) ranged from 5% at 200 nm to 30% 
at 330 nm and fell mainly in the 10% range.
