Comments: Quantum yields PHI of OH and HO2 in the ultraviolet photolysis of HO2NO2(peroxynitric acid, PNA) at 193 and 248 nm 
and that of NO3 at 193, 248 and 308 nm are reported. 
The quantum yields obtained at 296 K are: PHI 193 nm(OH)= 0.21 ± 0.12, PHI 248 nm(OH)= 0.085 ± 0.08, PHI 193 nm(HO2)= 0.56 ± 0.09, 
PHI 248 nm(HO2)= 0.89 ± 0.26, PHI 193 nm(NO3)= 0.35 ± 0.09, PHI 248 nm(NO3)= 0.08 ± 0.04 and PHI 308 nm(NO3)= 0.05 ± 0.02.
