title: Transmission of infrared radiation from flames by CO(2).
abstract: The transmission of infrared radiation from flames through various pathlengths of CO(2) was determined in the laboratory. The results show that a considerable amount of flame energy is transmitted in the regions 2.5 micro to 3.5 micro and 4.0 micro to 5.5 micro. For example, a cell length of 1500 cm of CO(2) at 760-mm pressure, equivalent to the CO(2) content in 50,000 m of atmosphere at sea level, transmitted 20% of the energy in the band region from 4.0 micro to 5.5 micro. Integrated transmittances for the bands at various pressures and cell lengths are presented in tabular form.
