Abstract

Saturated laser induced fluorescence is used for the sensitive detection of radicals in high pressure gases. The method and its application to a series of addition reactions of HO radicals in the high pressure regime are described. Experiments between 1 and 150 bar of the bath gas He allow for falloff extrapolations to the high pressure limit of the recombination reactions. Limiting rate constants (in cm³ molecule^-1 s^-1) of 2.2X10^-11 for HO+HO→H₂O₂, of 3.3X10^-11 for HO+NO→HONO, of 7.5X10^-11 for HO+NO ₂,HONO₂, and of 9.7X10^-13 for HO+CO→HOCO (and H+CO₂) are derived at 298 K.
