cds-question@unistra.fratomic-physicsThe interpretation of astronomical observations depends on the knowledge of accurate rest frequencies and intensities. The objective of this work is to provide spectroscopic data for the two ^13^C-isotopologues of dimethyl ether in the vibrational ground state. High-resolution rotational-torsional spectra of dimethyl ether-^13^C1 and dimethyl ether-^13^C2 have been measured in the laboratory covering frequencies up to 1.5THz. The analysis is based on an effective rotational Hamiltonian for molecules with two large amplitude motions.2013A&A...558A.112Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/558/A112CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/558/A112https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/558/A112http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/558/A112https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/558/A112https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/558/A112http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/558/A112GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/A+A/558/A112/transitionsExperimental transition frequencies of dimethyl ether ^12^CH_3_O^13^CH_3_ (table5) and ^13^CH_3_O^13^CH_3_ (table6)recnoRecord number assigned by the VizieR team.
