Laser photolysis of HNO3 at 222 nm: Direct determination of the primary quantum yield of OH

Article abstract of DOI:10.1063/1.450719

A method has been developed and used in the direct determination of the primary quantum yield of OH in the laser photolysis of nitric acid at 222 nm.The amount of laser light absorbed was ' determined with a calibrated disk calorimeter.The amount of OH produced was determined by absorption spectroscopy using the resonance line at 308.3 nm and a published value of its line strength.The primary quantum yield of OH at 296 K was found to be 0.89+/-0.08 (95percent confidence interval) with an uncertainty of + 17percent, - 8percent due to potential systematic errors.Within the experimental uncertainty, this result is consistent with a previous determination of a quantum yield of unity for the other product of photolysis, NO2.
