Paper Abstract
High resolution FT absorption spectrum of H2S in the near IR region from 10015 to 10323 cm-1 recorded at Kilt Peak
National observatory, USA, has been analyzed for the first time. Three interacting vibrational states: (103), (004), and
(400) belonging to the first pentadecade were considered. For the spectrum analysis the Watson-type rotational
Hamiltonian which takes into account the resonance interaction between involved vibrational states has been used. One
hundred forty four energy levels were reproduced from the fit with an average accuracy of 0.003 cm-1 for the main
isotope species using a set of 27 rotational and coupling parameters. New evaluation ofthe band origin of the dark (400)
state: E = 10292.493 cm-1 has been obtained from the fit to the upper state experimental energy levels which agrees
well with the value of the band origin calculated using the effective vibrational Hamiltonian [1]. As a result, the H2S
absorption spectrum was completely analyzed in region under study. The calculated line positions and transition
intensities are presented in the "ATMOS" information system. The obtained data on the hydrogen sulfide absorption
represent valuable information for investigation ofhighly excited states of H2S molecule.
