Abstract
The absorption spectra of $H_{2}S$ from 0.8 to $5 \mu m$ were recorded with spectral resolutions of 0.006, 0.012 and $0.021 cm^{-1}$ using the Fourier transform spectrometer at Kitt Peak National Observatory. Twenty bands were previously assigned so that accurate band origins and vibrational parameters could be determined [1]. The present paper will describe the analysis of the rotational structure of resonating $H_{2}S$ states between 3400 and $8000 cm^{-1}$. The energy levels of the second triad $(3700 cm^{-}1)$, first $(5100 cm^{-1})$ and second $(6200 cm^{-1})$ hexades and the first decade $(7500 cm^{-1})$ of ${H_{2}}^{32}S$, ${H_{2}}^{34}S$ and ${H_{2}}^{31}S$ will be reported along with Watson-type Hamiltonian parameters. Intensities measurements and dipole moment parameters for the lower polyad bands will also be given. Finally, the fourfold clustering of rotational levels belonging to the symmetric and asymmetric components of local mode manifolds at a higher degree of strectching excitation will be discussed.
