Abstract : Laboratory measurements of the absorption cross sections of NO2 at the temperature 298.5 K have been made throughout the wavelength region 360 nm to 470 nm. The equilibrium constant Kp has been experimentally obtained as 150 hPa, from which the column density of pure NO2 is obtained. The cross sections almost completely agree with the recent results of Merienne et al. The cross sections at the higher resolution of 0.14 cm-1 have been obtained in the wavelength region where the spectra have fine structure.
