| Abstract: | In this paper, the radiative fluorescence lifetimes of electronic excited states of NO2 were measured at six different excitation wavelength in the region of 513～520 nm. The dependence of the fluorescence lifetime on gas pressure and excited wavelength were also studied. By using the Stern-Volmer mechanism, the collision-free radiative lifetimes and collisional quenching rate constants were obtaind. The apparently anomalously long lifetime of NO2 was discussed with the perturbation theory. |
