We present line lists for ammonia (NH₃) at high temperatures obtained by recording Fourier transform infrared emission spectra. Calibrated line lists are presented for 12 temperatures (300°C-1300°C in 100°C intervals and 1370°C) and each line list covers the 740-2100/cm range, which includes the majority of the ν₂ umbrella bending mode region (11 µm) and the ν₄ asymmetric bending mode region (6.2 µm). We also demonstrate the useful technique of obtaining empirical lower state energies from a set of spectra recorded at different sample temperatures. Using our NH₃spectra, we have estimated lower state energies (E_Low in/cm) and our values have been incorporated into the line lists along with calibrated wavenumbers (∼ν in cm^–1) and calibrated line intensities (S' in cm/molecule) for each line. We expect our hot NH₃ line lists to find direct application in the modeling of planetary atmospheres and brown dwarfs.
