We report measured line intensities and temperature-dependent broadening coefficients of
NH 3 with Ar, N 2, O 2, CO 2, H 2 O, and NH 3 for nine sQ (J, K) transitions in the ν 2
fundamental band in the frequency range 961.5–967.5 cm− 1. This spectral region was
chosen due to the strong NH 3 absorption strength and lack of spectral interference from H 2
O and CO 2 for laser-based sensing applications. Spectroscopic parameters were
determined by multi-line fitting using Voigt lineshapes of absorption spectra measured with …
