Absorption Spectrum of Activated Nitrogen in the 600–1100-Å Region

Activated nitrogen produced by a microwave discharge has a large number of absorption bands in the 600–1100-Å region in addition to bands of ordinary nitrogen. The present analysis indicates that the additional bands belong to the same band systems as the ordinary nitrogen bands in this region, but the bands are produced by transitions from v>0 levels of the ground state. A brief note concerning the atomic absorption spectrum of nitrogen in the same region is included.
