Spatial distributions of OH emissions in the middle ultraviolet are observed in a laboratory hydrogen-air diffusion flame using a high resolution spectrometer in combination with a 512 channel diode array detector. Temperature measurements are made using a thermocouple. Using current reaction rates and diffusion coefficients the spatial dependence of OH and other major species are calculated using a version of the BOAT code, which was adapted for subsonic flow. The experimental observations are compared with these predictions. By using both experiment and theory, the major features of a laboratory hydrogen-air diffusion flame can be modeled. This combination of techniques is also applicable to methane-air diffusion flames.
