Part 2:Validation for line lists generated for nitric acid (H14N16O3) for the ν1 band and its first two associated hot bands (ν199, ν177) in the 2.8 μm region, the ν19, ν19 and ν17 bands at 3.2 μm, 2.5 μm and 2.4 μm, respectively

Résumé

This is the second of two back-to-back works, whose goal is to generate line lists for the ν1 band (3551.766 cm-1) and for the ν199 and ν177 hot bands for HNO3 in the 2.8 μm region. Also, we computed line lists for the weaker ν19, ν19, and ν17 bands, centered at 3093.53 cm-1, 4006.97 cm-1 and 4127.78 cm-1, respectively. While the first paper (Ref.[1], the preceding article in this issue), here labeled as "Part-1", was devoted to the description of the determination of the needed spectroscopic parameters in term of line positions and intensities, this paper describes the resulting line lists and the validation process. For this task, we use laboratory spectra recorded at high resolution and described in Part-1, together with the cross-sections established by the Pacific Northwest Laboratory at low resolution. Also, we use high resolution stratospheric solar occultation spectra recorded by the MkIV balloon-borne instrument of the NASA Jet Propulsion Laboratory (JPL). Similar inter-comparisons with laboratory or atmospheric spectra are also performed using the pseudo-line-list generated at JPL in 2005 and with the ab initio ExoMol list calculated by the University College of London. It proves that the line list generated during this work provides significant better agreements between observed and computed spectra.
