To support remote sensing of planetary atmospheres at 2 μm, laboratory spectra of NH3 and enriched 14NH3 and 15NH3 were recorded at 0.011 cm-1 resolution with the McMath Fourier transform spectrometer (FTS) located at Kitt Peak National Observatory/ National Solar Observatory. Multiple optical paths and pressures were used with sample temperatures between 297 and 185 K. Some 2000 line positions and intensities at room temperature were measured with precisions of 0.0003 cm-1 and 3%, respectively, for unblended transitions. Low and room temperature intensities were then combined to determine empirical lower state energies for 1815 lines. These data permitted the assignments for ν1+ν4 of 14NH3 to be extended to J'= 10. Transitions of ν3+ν4 of 15NH3 were also cataloged for the first time. Nearly 45% of the 2000 measured features were identified, and empirical upper state levels were obtained. The experimental results for lines with measured intensities greater than 3×10-24 cm-1/(molecule·cm-2) at 296 K were included in the 1996 HITRAN database. To obtain consistent NH3 line positions, the positions of 28 H2O transitions between 5206 and 5396 cm-1 were also calibrated using the 2-0 band of CO at 4260 cm-1.
