Paper Abstract

The hydrogen sulfide absorption spectrum in the 8400 - 8900 cm-1 spectral region, recorded at Kitt Peak National Observatory with Fourier transform spectrometer has been assigned and modeled within the effective Hamiltonian approach. Three hundred and fifty six precise energy levels were derived from the spectrum analysis for the (211), (112), (032), (131), and (230) states of the second decade. These levels were modeled using Watson-type rotational Hamiltonian with consideration strong Coriolis and weak Fermi resonance interactions. The RMS deviation of the fitting for the main H232S isotope species represented 0.006 cm-1 with 59 adjustable parameters. New evaluations of the vibrational energies Ev=8539.5617 cm-1 for the (131)-(000) band, Ev=8637.1601 cm-1 for the (032)-(000) band and Ev=8539.9253 cm-1 for the (230)-(000) band have been obtained. The line intensities were fitted with rms deviation of 15%. The results obtained are compared with recent study.
