Abstract:

The absorption by CO2 between 3100 and 4100 cm-1 has been studied with a spectrometer whose spectral slitwidth was approximately one-half cm-1. Spectral curves were obtained for 26 samples of CO2 and CO2 N2 with pressures as high as 14.6 atmospheres and with paths as long as 933 meters. Several absorption bands not observed previously in laboratory spectra have been identified and the strengths of several bands have been determined. Absorption between 3770 and 4100 cm-1 by the extreme wings of strong lines at lower wavenumbers has been investigated for self-broadened and N2-broadened lines. Spectral curves and extensive tables have been included for most of the samples.
