ABSORPTION BY CO2 BETWEEN 1800 AND 2850/CM (3.5-5.6 MICRONS)

Abstract

Transmission spectra in the 1800-2850/cm region were obtained for more than 100 samples of CO2 and CO2 mixed with N2 and A. The spectral resolution was 2.5/cm. Sample pressures varied from 0.0055 to 742 torr with absorber thicknesses covering the range from 0.081 to 84,400 atm cm. Spectra of several samples at the lower pressures show the effect of Doppler broadening. Measurements in the 2400-2560/cm region provide information about the absorption by the extreme wings of collision-broadened lines. Replotted transmission spectra and extensive tables of integrated absorptance for 116 samples are included.
