The 5.8 µm absorption bands for nitric acid (H14N16O3): line positions and intensities for the ν2 band at 1709.567 cm−1 and for its first associated hot bands (ν2+ν9−ν9, ν2+ν7−ν7, ν2+ν6−ν6)

This paper is the second of two back-to-back works, whose goal was to generate a more accurate linelist for the 5.8 µm absorption band of HNO₃. Here, we report improved line positions and intensities in the ν₂ cold band which is the main band in this region. For this, we recorded four high-resolution Fourier transform spectra for the ν₂ band, centered at 1709.567 cm⁻¹, under different experimental conditions. Using these spectra, a new extended line position analysis was performed for the ν₂ band, leading to more accurate line positions. In parallel, individual line intensities were measured. It appears that, although the ν₂ band is mainly of B-type, it also possesses a (very) weak A-type component that cannot be ignored. Overall, the line intensities in this new database are about 8% weaker than those quoted presently in the HITRAN () or GEISA () databases. Our final linelist for HNO₃ at 5.8 µm is provided as a supplement to this paper. It includes lines from the ν₂ band together with those of the ν₂+ν₉−ν_9, ν₂+ν₆−ν₆, and ν₂+ν₇−ν₇ associated hot bands that were generated during the first part of this study, described in the companion paper.
