“…Fig. 4 shows a 'low dispersion' spectrum of a laboratory path of ammonia measured by Giver et al (1975), where we hand-digitised the spectrum shown in their Fig.3 and which we previously showed in Fig. 2 of Irwin et al (2018).…”

“…To compare the line data of the ExoMol-C2018 line database with the measurements in more detail, we hand-digitised the published high-resolution (quoted spectral resolving power R ∼ 170,000) laboratory spectra of Giver et al for the 6475Å band (shown as Fig.1 of Giver et al 1975) for a low pressure path of length 400m, pressure 0.061 atm and temperature 294K. Giver et al (1975) showed these spectra spread over three pages and we repeat this format here, comparing our digitised version with line-by-line-calculated spectra in Figs 6 -8. We find that spectra calculated 3 with the line data of Giver et al (1975) have absorption lines that match the position and strength of many of the stronger measured lines, for example at 6449.95Å and 6457.05Å, but that many are not represented; this is entirely as expected since these line data were only published for the thirty-three strongest lines.…”

An analysis of currently available ammonia (NH 3 ) visible-to-near-infrared gas absorption data was recently undertaken by Irwin et al. (Icarus, 302 (2018) 426) to help interpret Very Large Telescope (VLT) MUSE observations of Jupiter from 0.48 -0.93 µm, made in support of the NASA/Juno mission. Since this analysis a newly revised set of ammonia line data, covering the previously poorly constrained range 0.5 -0.833 µm, has been released by the ExoMol project, "C2018" , which demonstrates significant advantages over previously available data sets, and providing for the first time complete line data for the previously poorly constrained 5520-and 6475-Å bands of NH 3 . In this paper we compare spectra calculated using the ExoMol-C2018 data set with spectra calculated from previous sources to demonstrate its advantages. We conclude that at the present time the ExoMol-C2018 dataset provides the most reliable ammonia absorption source for analysing low-to medium-resolution spectra of Jupiter in the visible/near-IR spectral range, but note that the data are less able to model high-resolution spectra owing to small, but significant inaccuracies in the line wavenumber estimates. This work is of significance not only for solar system planetary physics, but for future proposed observations of Jupiter-like planets orbiting other stars, such as with NASA's planned Wide-Field Infrared Survey Telescope (WFIRST).

“…Several high energy band centers at 12 0 0 0, 15 0 0 0 and 18 0 0 0 cm −1 were also included from the early work of Coy and Lehmann [27] which, at the time of performing our calculations, were the only assigned spectra above 12 0 0 0 cm −1 available in the literature. We also note the unassigned 5 ν 1 absorption bands of NH 3 by Giver et al [38] .…”
