Absorption spectra of pure CO₂ have been recorded in the vicinity of the 2675 cm⁻¹ Fermi triad for temperatures between 211 K and 296 K. The 2ν₁, ν₁ + 2ν₂, 2ν₂ collision-induced components have been extracted from the measured spectra, including for the low frequency band at 2547 cm⁻¹, which is strongly masked by the ν₃ wing absorption. Dimeric features are clearly seen on top of the structureless profiles. Integrated intensities of the Fermi-triad components are determined as a function of temperature.
