Comments: Absolute quantum yields for the formation of OH radicals in the laser photolysis of aqueous solutions of NO3 -, 
NO2 - and H2O2 at 308 and 351 nm and as a function of pH and temperature have been measured.
H2O2- photolysis: 
308 nm, 298 K, PHI(OH) = 0.98 ± 0.03 for pH = 7
351 nm, 298 K, PHI(OH) = 0.96 ± 0.04 for pH = 7.
