Abstract

He- and N₂-broadening coefficients have been measured for the lines Q2 to Q22 of the V₁-V₂ (10⁰01 ← 01¹01) band of CO₂ near 720.80cm^-1, using a tunable diode-laser spectrometer. The collisional widths have been obtained at low perturber pressures by fitting Voigt and Galatry profiles to the measured shapes of the lines. Spectra in the V₁-V₂ band of CO₂ in mixture with He and N₂ have also been recorded at higher pressures. The deviations observed from an additive superposition of Lorentzian lines have been notably reduced by considering collision-induced line-mixing effects.
