The Excitation Mechanism of the Nitrogen First Positive and First Negative Radiation at High Temperature

Abstract

The kinetic mechanisms responsible for the excitation of the first positive and first negative emission of nitrogen have been investigated in a re- examination of previously reported shock-tube measurements of the non- equilibrium radiation for these systems. The rate coefficients of the collisional quenching reactions were found to be given by empirical expressions over the approximate temperature range 6000 - 14000K.
