Abstract:
Room-temperature cavity ring-down spectra (CRDS) of hydrogen sulfide were recorded at three pressures of 10, 20, and 30 Torr in the 12950–13300 cm-1 range with a sensitivity on the order of 3 × 10-11 cm-1 in terms of the absorption coefficient and analyzed. The line positions and intensities are derived from these spectra. The theoretical simulation of these spectra was performed within the method of effective operators. The measured line positions and intensities are compared with the variational calculated values. Considerable difference between calculated (Azzam A.A.A., Yurchenko S.N., Tennyson J., Naumenko O.V. Exomol line lists XVI: A hot line list for H2S // Mon. Not. R. Astron. Soc. 2016. V. 460. P. 4063–4074) and observed line positions and intensities is found.
