The emission of a cold plasma of a mixture of $H2$ and $N2$ flowing through a reactor and excited by a R. F. discharge has been recorded from 2$000cm-1$ to $4000cm-1$ under Doppler-limited resolution with the High Information Fourier transform spectrometer of Laboratoire d’Infrarouge. The observation of the rotation-vibration bands 1-0, 2-1, 3-2, 4-3, 5-4 of $\mathrm{<mrow\; data-mjx-texclass="ORD">14</mrow>}NH$ in its $X-\Sigma$ fundamental electronic state is reported.
