Abstract

Broadening of the spectral lines by resonance and Van der Waals forces in the Schumann–Runge system of O2, the first and second positive systems of N2, the beta and gamma systems of NO and the first negative system of N2+ is treated by means of the impact approximation. At temperatures of 1000°K and higher, the broadening effect of the resonance forces is negligible; there is hence no J dependence in the widths. Van der Waals constants are calculated for the electronic–vibrational levels of interest using available discrete and continuous oscillator strengths. Half-widths in the various systems have been computed for 0<¯v,v<¯12, 1000°K T 18,000°K and ρ/ρ0 = 10,10−1. In general, there is not much width variation with vibrational band in a system.
