  High-resolution absorption spectra of \NH\ in the region 2100 - 5500 \cm\ at
1027 $^{\circ}$C and atmospheric pressure (1045 $\pm$ 3 mbar) are measured. An
\NH\ concentration of 10\% in volume fraction is used in the measurements.
Spectra are recorded in a high-temperature gas-flow cell using a Fourier
Transform Infrared (FTIR) spectrometer at a nominal resolution of 0.09 \cm. The
spectra are analysed by comparison to a variational line list, BYTe, and
experimental energy levels determined using the MARVEL procedure. 2308 lines
have been assigned to 45 different bands, of which 1755 and 15 have been
assigned or observed for the first time in this work.
