Description

Synthetic spectra of the N₂+ first negative system are given for general reference in auroral studies. The material presented illustrates the appearance of the major band sequences (Δv = 0, -1, -2, -3 and +1) at various N₂ x ground state rotational and vibrational temperatures ranging from 200 to 5000°K, and the appearance of the major bands (3914 A, 4278 A, 4709 A) at various resolutions ranging from ~.3A, when the R-branch is completely resolved, to smooth band profiles. Also shown are sample band profiles generated in an auroral arc with a model atmospheric temperature and volume emission rate. An appendix contains tables of the calculated band intensities and the line wavelengths and intensities for selected bands.
