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.
