TEMPERATURE DEPENDENCE OF CHEMILUMINESCENT REACTIONS .I. NITROGEN AFTERGLOW

Using the glow discharge shock tube recently developed in this laboratory, we measured the temperature and density dependence of the Lewis-Rayleigh afterglow between 300° and 2400°K. We also determined the absolute efficiency, i.e., the rate constant of this chemiluminescent reaction. Our results can be represented by the following expression: I=0.60×10 -17(T/300)-0.09[N]2 photons/cm 3·sec. The value of the integrated rate constant given includes all radiation between 500 and 700 nm.
