Abstract An experimental apparatus using an AC discharge was developed for producing molecular ion beam. The emission spectral intensity of N+2 is stronger than that of N2, and a very high ratio of N+2(B)/N2(C) up to 6∶1, was achieved in N2 discharge. The effects and processes of N2 discharge, and the concentration modulation spectra were studied. The vibrational temperature and rotational temperature of N+2 molecular ions beam were calculated to be 3 310 and 282 K respectively from the emission spectra.
