Paper Abstract

The high resolution absorption spectra of H2S have been recorded in the region 7200-7890 cm-1 with the McMath Fourier transform spectrometer located at Kitt Peak National Observatory. A careful analysis of the spectra led to derivation of 1080 precise energy levels for the 1st decade interacting states of H232S, H233S, and H234S isotope species. The energy levels were introduced into a least squares fit using a Hamiltonian which takes into account Coriolis, Darling-Dennison and Fermi-resonance interactions. Precise rotational and coupling parameters have been determined which reproduce the experimental energy levels with 0.0015 cm-1 for the main isotope species. The experimental band origin Ev=7419.9162 cm-1 for the super weak (220)-(000) band was obtained for the first time from the simultaneous analysis of cold (220)-(000) and hot (220)-(010) bands. Detailed and accurate H2S absorption line list was generated in the HITRAN format for the first decade spectral region.
