Abstract

We present line lists for ammonia (NH_3_) at high temperatures obtained by recording Fourier transform infrared emission spectra. Calibrated line lists are presented for 12 temperatures (300{deg}C-1300{deg}C in 100{deg}C intervals and 1370{deg}C) and each line list covers the 740-2100cm^-1^ range, which includes the majority of the {nu}_2_ umbrella bending mode region (11um) and the {nu}_4_ asymmetric bending mode region (6.2um). We also demonstrate the useful technique of obtaining empirical lower state energies from a set of spectra recorded at different sample temperatures. Using our NH_3_ spectra, we have estimated lower state energies (E_Low_ in cm^-1^) and our values have been incorporated into the line lists along with calibrated wavenumbers (\tilde{nu} in cm^-1^) and calibrated line intensities (S' in cm/molecule) for each line. We expect our hot NH_3_ line lists to find direct application in the modeling of planetary atmospheres and brown dwarfs.
