Abstract
The intensity distribution was measured for the rotational lines of the N2 molecule in the radiation of a glow discharge in the pure gas, at pressure 0.1–5 torr, or with argon, at a total pressure of 2 torr, at a current of 40 mA. The distribution found lags behind a Boltzmann distribution in the 0–3 band (corresponding to the C3π-B3π transition; the second positive system) over the pressure range 0.1–2 torr and in the 1–4 band (the C3π-B3π transition; second positive system) at a pressure of 0.1 torr. In the N2 + Ar mixture there is selective amplification of the J=25, 26 rotational lines.
