Abstract

The high–resolution infrared spectrum of the HDS isotopologue was recorded and analyzed in the region of the ν 2 fundamental band region (700–1400 cm −1 ) with a Bruker IFS 125HR Fourier transform infrared spectrometer (Zurich prototype ZP2001). Among the lines of the ν 2 band of the HD 32 S and HD 34 S molecules, 801 transitions of HD 33 S were found in the spectrum and assigned for the first time (J max = 19 and K a max = 12). Also for the first time, rotational energies of the ground vibrational state were determined from the 87 ground state combination differences obtained from the experimental data. Fits of parameters of the Watson hamiltonian with both ground state combination differences and ro–vibrational energy values (line positions) of the (010) vibrational state were made. Parameters of the effective dipole moments of the pure rotational transitions and of the ν 2 band are obtained. Line lists (line positions and line strengths) of the pure rotational transitions and transitions belonging to the ν 2 band are generated which can be useful for astrophysical and planetological applications.
