Complex Investigation of the Absorption and Emission Spectra of Carbon Dioxide

详细

Absorption and emission spectra of carbon dioxide are measured and analyzed for temperatures 220–2500 K in the spectral range 1–25 μm. Intensities and half-widths of the spectral lines are determined and hightemperature atlas of the spectral lines’ parameters is compiled. Based on the developed mathematical model, the parameters of spectral transmission functions of СО₂ are obtained at different temperatures in the vibration-rotation and pressure-induced bands of СО₂. Practical application of the obtained radiative characteristics is considered for solving problems of radiative heat exchange in planetary atmospheres and high-temperature media and designing optoelectronic systems intended for aero carriers monitoring.
