| Description | Mercury traces and synthetic air were introduced into a nitrogen dc glow discharge under the pressure of 700 Pa. The influence of added oxygen and mercury traces is substantially different. It also depends on time elapsed from the decay beginning. The decay processes are predominantly governed by mercury up to about 25 ms while the later period is apparently influenced by oxygen. Molecular oxygen is fully dissociated in an active discharge (residence time of about 8 ms) and due to its low concentration the NO species are formed, only. These species significantly depopulate the highly vibrationally excited nitrogen electronic ground state molecules, and thus the kinetics is significantly changed. The influence of mercury atoms on the kinetics is under the study up to now. Other metals will follow. |
