Abstract:

Absolute absorption cross sections of nitrogen dioxide were measured with a resolution of 0.008 nm in 470-490, 520-534, 588-601, and 603-616 nm spectral regions at temperatures of 295, 573, and 673K. An absolute error of - 10 is due principally to uncertainty in the NO2 concentration. Absorption cross sections were also measured at these temperatures in the 450-650 nm spectral region with a resolution of 0.075 nm with an error of - 10. All data were corrected for thermal decomposition of NO2 at the elevated temperatures. The spectral features show broadening at elevated temperatures consistent with the breakdown of delta K selection rules for higher rotational levels.
