Abstract: The infrared emission spectrum produced by glow discharge in nitrogea was studied with a spectral resolution of $0.12 cm^{-1}$. A complete rotational structure of the P, Q, and R brunch was obtained for the $\nu^{1}\Delta_{4}-e^{1}\pi_{4} $ (0-0) band at $2740 cm^{-1}$ of which McFarlane under a partial observation in his laser-type $experiment.^{1}$ The emission feature at $2470 cm^{-1}$ was found to be the atomic N I $5g\rightarrow 4f$ $transition.^{2}$ For the $W^{3}\Delta_{u} -B^{3}\pi_{g}$ transition, we were able to observe only the band at $3006 cm^{-1}$. No triplet structure were indicated in our data at $2740 cm^{-1}$, in contrast to the recent results reported by Ceray et $al.^{3}$ The spectroscopie constants for the $w^{1}\Delta_{u} -a^{1}\pi_{g}$ (0-0) band obtained from our data ore: \begin{eqnarray*} \Delta T = 2T47.15 \mbox{cm}^{-1} \\ B^{\prime} = 1.4884 \mbox{cm}^{-1} \\ D^{\prime} = 0.293 \times 10^{-5} \mbox{cm}^{-1} \\ B’‘ = 1.6052 \mbox{cm}^{-1} \\ D’‘ = .369 \times10^{-5} \mbox{cm}^{-1} \end{eqnarray*} We found them in a good agreement with the previously measured $values.^{*}$
