Abstract: The second positive system (C³Πu - B³Πg) for N₂ has been widely used for optical diagnostics in plasma systems, hypersonic environments, and astrophysics. To this end, a spectrally accurate linelist has been generated for the second positive band system. Ab initio potential energy curves (PECs) and the transition dipole moment (TDM) from Ni and Cheng [1] have been used to calculate new electronic-vibrational transition moments, extending up to v = 29 for the B³Πg, using the DUO program. Spectral constants from Western et al. [2] and Roux et al. [3] have been compiled along with the new electronic-vibrational transition moments in PGOPHER software to generate the new linelist. Comparisons to experimental data and the SpecAir software have been used to validate the new linelist. Sandia National Laboratories is a multimission laboratory managed and operated by National Technology & Engineering Solutions of Sandia, LLC, a wholly owned subsidiary of Honeywell International Inc., for the U.S. Department of Energy’s National Nuclear Security Administration under contract DE-NA0003525.
