VizieR Online Data Catalog: Isotopic H2CS laboratory spectroscopic study (Mueller+,
Abstract
We investigated the laboratory rotational spectra of numerous isotopic species in natural isotopic composition almost continuously between 110 and 377GHz. Individual lines were studied for most species in two frequency regions between 566 and 930GHz. Further data were obtained for the three most abundant species in the 1290-1390GHz region.
New or improved spectroscopic parameters were determined for seven isotopic species. Quantum-chemical calculations were carried out to evaluate the differences between ground state and equilibrium rotational parameters to derive semi-empirical equilibrium structural parameters. The spectroscopic parameters are accurate enough for predictions well above 1THz with the exception of H213C34S where the predictions should be reliable to around 700GHz.
