Abstract: | The absolute populations of the vibrational levels of the B3Πg and C3Πu states in an rf nitrogen discharge are calculated from the quantum yields of the 1+ and 2+ systems in the discharge, and the “excitation temperature” of these states is measured. Emission spectroscopic methods are used to determine the vibrational and rotational temperatures of the C3Πu state, as well as the vibrational temperature of the B3Πg state. These data are used to estimate the vibrational temperature of the X′∑ g + state and the stored energy in the activated nitrogen, and to examine the mechanism by which translational-vibrational degrees of freedom are excited in nitrogen molecules in the discharge. |
