The transmission of infrared radiation from flames through various pathlengths of CO2 was determined in the laboratory. The results show that a considerable amount of flame energy is transmitted in the regions 2.5 μ to 3.5 μ and 4.0 μ to 5.5 μ. For example, a cell length of 1500 cm of CO2 at 760-mm pressure, equivalent to the CO2 content in 50,000 m of atmosphere at sea level, transmitted 20% of the energy in the band region from 4.0 μ to 5.5 μ. Integrated transmittances for the bands at various pressures and cell lengths are presented in tabular form.
