Abstract
Hydroxyl radical (OH) is measured using laser induced fluorescence in reduc ed pressure, on-premixed, opposed flow CH4/air flames inhibited by either N -2, CF3Br, or Fe(CO)(5). Emission spectroscopy is used to qualitatively mon itor OH for each inhibited flame as well as to characterize the structure o f a Fe(CO)(5) inhibited flame. For the flames to which CF3Br and Fe(CO)(5)a re added, the OH population decreases approximately proportional to the amo unt of inhibitor agent added. OH populations decrease faster for flames inh ibited by Fe(CO)5 than for flames inhibited by CF3Br.
