发现在约1200 K下NO2的热发射光谱与NO+ 03的化学发光光谱相似。结果表明，这些光谱是NO2分子同一电子激发态的相似低振动能级到基态的跃迁。由Hg 4358 A辐射激发的0+ NO化学发光和NO2荧光涉及从NO2的相同激发态的更高振动能级到基态的跃迁。在总压为0.8 ~ 3.0mm Hg，温度为216 ~ 322 K的流动系统中，研究了NO+ 03体系的荧光发射动力学和反应动力学。反应机理U 7如图所示为：
The spectrum of the thermal emission of NO2 at about 1200 K was found to be similar to that of the NO+ 03 chemiluminescence. It is concluded that these spectra are transitions from similar low-lying vibrational levels of the same excited electronic state of NO2 to the ground state. The 0+ NO chemiluminescence and NO2 fluorescence excited by Hg 4358 A radiation involve transitions from higher vibrational levels of the same excited state of NO2 to the ground state. The kinetics of chemiluminescent emission and of overall reaction in the NO+ 03 system have been studied in a flow system at total pressures between 0.8 and 3.0 mm H g and temperatures from 216 to 322 K. The reaction mechanism u7as shown to be
