A new high-resolution spectroscopic study of the 0—0 transition (3371 Å) in the N2 Second Positive System excited by a pulsed transverse electrical discharge has been carried out with a 14-m Czerny-Turner spectrograph. A detailed rotational analysis of the spectrum has pointed out a few misassignments in the earlier work of Dieke and Heath. The simple model proposed by Patel has been applied to the nitrogen laser in order to explain the optical gain formation on the different branches. The experimental results are in reasonable agreement with the theoretical model.
