Polarization spectroscopy measurements of O2 Schumann-Runge absorption are presented. The measurements are carried out in the resonator of a microwave-powered plasma torch operated with O2 at atmospheric pressure. A line-by-line spectral simulation code is developed in order to validate the measured spectra at the expected translational, rotational, and vibrational temperatures K and K. The results show very good agreement with the spectral features of the measured O2 polarization spectra. The range of probed vibrational and rotational transitions confirms the feasibility of polarization spectroscopy as a quantitative diagnostic tool for various applications.
