Investigation of Absorption and Emission Spectra of Nitrogen Oxides NO, N2O, NO2, and N2O4

The absorption and emission spectra of NO, N2O, NO2, and N2O4 nitrogen oxides have been studied with high and intermediate spectral resolution in the range 0.25–25 μm under conditions of self-broadening and nitrogen-induced broadening at room and enhanced temperatures. The experimental data on the spectral transmittance function have been parameterized by the two-parameter equivalent mass method. The rovibrational band intensities have been measured and the data on the absorption induced by the pressure in collisions of NO2–NO2 molecules have been obtained.
