Abstract
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 2ν 1, ν 1 + 2ν 2 , 2ν 2 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 v 3 wing absorption. Dimeric features are clearly seen on top of the structureless profiles. Integrated intensities of the Fermi-triad components are deter- mined as a function of temperature.
