摘要：
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 degrees C in 100 degrees C intervals) and each line list covers the 1650-4000 cm(-1) range, which includes the nu(1) and nu(3) fundamental modes (3 mu m) plus a number of combination, overtone and hot bands. Using our NH3 spectra, we have estimated empirical lower state energies (E-Low in cm(-1)) and our values have been incorporated into the line lists along with line positions ((nu) over bar in cm(-1)) and calibrated line intensities (S' in cm/molecule). We expect our hot NH3 line lists to find direct application in the modeling of planetary atmospheres and brown dwarfs. (C) 2012 Elsevier Ltd. All rights reserved.
