High-Resolution Fourier Transform Spectra of HDS in the Regions of the Bands ν₁and 2ν₁/ν₂+ ν₃

Abstract

High-resolution spectrum of the HDS molecule was recorded with the Bruker Fourier spectrometer in Oulu in the regions of the ν₁and 2ν₁/ν₂+ ν₃absorption bands. Fine rotational structure of the ν₁band was analyzed with the model of an isolated vibrational state, while in the analysis of the 2ν₁and ν₂+ ν₃bands it was necessary to take into account the resonance interactions between these two bands. Comparison of the experimentally determined parameters is made with the deductions of the expanded local mode approach.
