Title: Collision-Induced Absorption in the CO2 Fermi Triad for Temperatures From 211 K to 296 K
Published: July 01, 2003
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 2υ1, υ1 + 2υ2, 2υ2 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 υ3 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.
