ABSORPTION BY CO2 BETWEEN 6600 AND 7125/CM (1.4 MICRON REGION)

Abstract

The absorption by CO2 in the 6600 - 7125/cm region (near 1.4 microns) has been studied with a spectrometer having a spectral resolution of about 1/ cm. Spectra were obtained for 38 samples of CO2 and CO2 + N2 with pressures as high as 15 atmospheres and paths as long as 933 meters. The strengths of the important bands and the half-widths of several lines have been measured. Photographs of the spectra of all the samples as well as a table of transmittance versus wavenumber are included.
