The aim of this paper is to present the modification of the emission spectral lines of Ar at the addition of various amount of N-2. Because the post luminescence discharge contains atoms and molecules in excited states at gas pressures between 10-100 torr and the temperature of the flowing after glow plasma is low, we expect to have specific radiation of the excited atoms and molecules as we reported before for electropositive- (noble gas) and electronegative (H-2) gas mixtures. Preliminary results sustain our expectation, the recombination plasmas, enhancing the intensity of some peculiar lines of the gases as in the case of M-effect when the gas mixture is Ar+N-2. The obtained data add new results sustaining our hypothesis of ion-ion recombination in the electronegative-electropositive gas mixtures generating M-effect.
