Energy levels, transition frequencies and Einstein A coefficients for the fine structure line spectrum of the ³P ground state of N⁺ without hyperfine structure are taken from the NIST database.

Collision rates with electrons are taken from Tayal (2011) and were calculated for temperatures in the range from 500 to 100,000 K.

Collision rates with atomic H are from Yan & Babb (2023) and cover temperatures in the range from 10 to 10,000 K.
