Abstract A numerical model is constructed to calculate the number densities of some excited species of nitrogen in low-pressure discharge nitrogen plasma, together with simultaneous solution of the self-consistent electron energy distribution function and N2-vibration distribution function. We consider species N2(X), N2(A), N2(B), N2(C), N2(a), N2(a'), N2+, N4+, N(4S) and e-. In addition to electron collisional reactions, diffusion losses and molecular relations are included. It is found that the ratio of number densities of N2(B) and N2(C) states can be a good measure of the electron kinetic temperature. The N2(C) state is found to be almost in a corona equilibrium, whereas the N2(B) state becomes mainly populated by N2(X, v ≥ 6) + N2(A) reaction and depopulated by collisional relaxation by the ground-state N2(X) molecule.
