O2-broadening coefficients of acetylene lines in the ν4 + ν5 band at room temperature

Research output: Contribution to journalArticle

Abstract

Abstract Room temperature O<inf>2</inf>-broadening coefficients were measured for 16 transitions, from P(23) to R(16), of the ν<inf>4</inf> + ν<inf>5</inf> band of acetylene near 7.5 μm. Absorption spectra of these lines were recorded at room temperature and various pressures, from 20.00 mbar to 66.21 mbar using a tunable diode laser spectrometer. The broadening coefficients were obtained by fitting the Voigt profile as well as the Rautian, the Galatry and the quadratic Speed Dependent Voigt models on the experimental spectra. The results were then compared with some previous studies realized for other bands of acetylene.
