Laser optogalvanic and emission spectrum of N2 in the 5400–6150 Å region
Laser optogalvanic (LOG) and emission spectra of the N2 molecule have been recorded at different discharge voltages and gas pressures in the spectral region 5400–6150 Å. It is observed that in the optogalvanic spectrum bands belonging to several systems develop extensively. Under the present discharge conditions bands of the first positive system are predominant. The variation of the signals with pressure and voltage in the two cases is discussed.
