OH-concentration distributions and temperature profiles have been measured on a premixed propane-air flame by laser deflection techniques. Photothermal deflection spectroscopy has been utilized for the measurement of the OH radical. Both a low-spatial-resolution (near collinear) and high-spatial-resolution (crossed-beam) scheme were used to profile the premixed flame. An optoacoustic deflection technique was utilized for thermometry. Both average-temperature profiles and probability distribution functions were determined by this technique. A comparison with data obtained by the CARS technique demonstrated that no significant flame perturbation was occurring.
