Résumé

Using a tunable diode-laser spectrometer, we have measured the CO ₂-broadening coefficients of 28 absorption lines in the ^ν4 band of CH₄. Each line was recorded at room temperature (296 K) and at 4 different pressures, ranging from 8 to 50 mbar. The experimental determination of the CO₂-broadening coefficients was performed by fitting a theoretical profile to the experimental profile of each line recorded at each pressure. Voigt, Rautian-Sobel'man and Galatry models were therefore used. The impact of these determinations on atmospheric investigations on CO₂-rich planetary atmospheres are addressed. © 2014 Elsevier Inc.
