Abstract
Transmission spectra for hot ammonia (23-700 $^{\circ}$C) have been recorded in the region 5500-8800 $\wn$ and line lists have been produced from these spectra that include line positions, intensities and empirical lower state energies. Transmission spectra were obtained at high resolution (0.02 \wn) by recording absorption, emission and background spectra using a Bruker IFS 125HR with a hot quartz cell heated by a tube furnace. Temperature-appropriate line lists for the 2500-5500 $\wn$ region have been completed and assignment of both regions is undwer way. These empirical line lists will be compared to the theoretical line lists for ammonia available from the ExoMol project and can be used in efforts to model the atmospheres of exoplanets and brown dwarfs.
