Abstract:

The absorption by 38 different samples of CO2 in the 4500 - 5400cm near 2 microns region was studied with the use of a spectrometer having a spectral resolution between approximately 0.3 and 1cm. Samples of CO2 and CO2 N2 were contained in two different absorption cells one having a maximum path of 933 meters and used at a maximum pressure of 2.5 atm. The other was used at paths as long as 32.9 meters and at pressures as high as 15 atm. Photographs of the spectra of every sample as well as a table of transmittance versus wavenumber are included. Also presented is a table of the integrated absorptance versus wavenumber, where approximately 600 values are tabulated for the largest samples.
