We have developed a technique for generating high concentrations of gaseous OH radicals in a reaction chamber. The technique, which involves the UV photolysis of O 3 in the presence of water vapor, was used in combination with the relative rate method to obtain rate constants for reactions of OH rad

โฆ Synopsis
Analysis o[ absorption spectra o/ OH ~n detonations of C2H2+H2+202 at initial pressures of 120 mm and 180 mm of mercury has given both the rotational temperature and the absolute concentration of OH.
The experimental rotational temperatures calculated by taking into account the rotation-vibration interaction in electronic transitions have agreed with the values calculated from detonation theory. Also, the experimental OH concentrations calculated by using Dyne" s value of F and a= l.O for 120 mm of mercury or a= l.5 for 180 mm of mercury have agreed with the values calculated from. detonation theory.
