We present further line lists of ammonia (NH3) at high temperatures obtained by recording Fourier transform infrared emission spectra. Calibrated line lists are presented for 12 temperatures (300-1400 °C in 100 °C intervals) and each line list covers the 1650-4000 cmâ1 range, which includes the ν1 and ν3 fundamental modes (3μm) plus a number of combination, overtone and hot bands. Using our NH3 spectra, we have estimated empirical lower state energies (ELow in cmâ1) and our values have been incorporated into the line lists along with line positions (Î½Ë in cmâ1) and calibrated line intensities (Sâ² in cm/molecule). We expect our hot NH3 line lists to find direct application in the modeling of planetary atmospheres and brown dwarfs.
⺠High temperature line lists of ammonia at have been recorded in the infrared. ⺠Spectra were recorded using a tube furnace and FT-IR spectrometer. ⺠Line lists contain fundamental (ν1,ν3), overtone, combination and hot NH3 bands. ⺠Empirical lower state energies for a large number of lines have been estimated. NH3 HITRAN lines have been included in the final temperature specific line lists.
