L., Domínguez Gómez, R., Carvajal Zaera, M., Hochlaf, M.: "Accurate spectroscopic characterization of ethyl mercaptan and dimethyl sufide isotopologues : a rute toward their astrophysical detection". The Astrophysical Journal, Vol. 796, n. 1 (2014). ISSN 0004-637X0004-637X1538-4357 (electrónico)http://hdl.handle.net/10272/9166Using state-of-the-art computational methodologies, we predict a set of reliable rotational and torsional parameters for ethyl mercaptan and dimethyl sulfide monosubstituted isotopologues. This includes rotational, quartic, and sextic centrifugal-distortion constants, torsional levels, and torsional splittings. The accuracy of the present data was assessed from a comparison to the available experimental data. Generally, our computed parameters should help in the characterization and the identification of these organo-sulfur molecules in laboratory settings and in the interstellar medium.engAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/AstrochemistryCatalogsISM: abundancesISM: moleculesMolecular datajournal article10.1088/0004-637X/796/1/50open access
