This paper presents proof-of-principle research for local temperature measurement based on the rotational spectrum obtained by Radar REMPI (Resonance Enhanced Multi- Photon Ionization) of nitric oxide. Radar REMPI can achieve a time accurate, highly sensitive, extremely selective and non-intrusive spectral measurement of trace species. Nitric oxide is a convenient molecule for the measurement of temperature because its electronic states are easily accessible to tunable UV lasers and its diatomic structure makes the rotational and vibrational spectra relatively simple. It is a trace constituent of air and a product in combusting environments. In this paper a comparison between temperature dependent experimental and theoretical (2+1) rotational REMPI spectra ( v′=0 - v″=0) of nitric oxide is given. The theoretical model achieves good agreement with the reference spectra, and a fit to the measured spectrum yields the rotational temperature in a room temperature experiment. Measurements in flames require further investigation.
