Abstract

The absorption by pure CO2 beyond the ν3 bandhead has been measured with a grating spectrometer. Experiments have been made in the 0–60-bar and 291–751-K pressure and temperature ranges. Our room temperature determinations are in good agreement with previous ones and the measured temperature dependence above room temperature is consistent with recent determinations below 300 K. Lorentzian calculations, modified by the introduction of a line shape corrective factor χ, are presented. Good agreement between the observed and calculated spectra is obtained when a temperature independent χ factor, determined by Cousin et al. at 296 K, is used.
