Room temperature spectral shape parameters of self-broadened Oxygen A-band transitions from multiple FTS-spectrum fits


In this work, the spectral shape profiles of 60 Oxygen A band transitions were studied using the Voigt and the quadratic-speed-dependent Voigt profiles with taking account the contribution of the first order of the line-mixing effects. Seven-teen transmitted spectra of pure oxygen were recorded at room temperature and pressures ranging from 408.11 to 998.82 mbar using a Furrier transform spectrometer. The spectroscopic parameters of each line-shape model used were then retrieved from measured spectra using a multi-spectrum fitting procedure. The obtained results show that our results are in good agreement with those of other studies.
