cds-question@unistra.fratomic-physicsmillimeter-astronomysubmillimeter-astronomyspectroscopyThe rotational-torsional spectrum of the syn conformer of methyl carbamate [CH_3_OC(:O)NH_2_], an isomer of the essential amino acid glycine [NH_2_CH_2_C(:O)OH], has been recorded at room temperature in the spectral region from 79 to 371GHz. Methyl carbamate possesses a methyl group internal rotor, which gives rise to A and E torsional substates, and associated splittings in the rotational spectrum. Almost 6000 new rotational transitions arising from the vibrational ground state have been assigned, about half of them belonging to the E torsional substate. The Fast Scan Submillimeter-wave Spectroscopic Technique (FASSST) spectrometer at the Ohio State University was used for the present measurements2007ApJS..169...28Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/169/28CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/406/L47 : 17OH spin-rotation transition frequencies (Polehampton+ 2003)J/ApJ/500/1059 : Dimethyl ether transitions frequencies (Groner+, 1998)J/ApJS/162/428 : n-propanol transition frequencies (Maeda+, 2006)J/ApJS/166/650 : mm/submm spectrum of iso-propanol (Maeda+, 2006)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/169/28https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/169/28http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/169/28https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/169/28https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/169/28http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/169/28GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalRadiodefaultJ/ApJS/169/28/table2Assigned and fitted rotational transition frequencies of methyl carbamate in its ground vibrational stateKa2The K_a_ lower statephys.atmol.qnintKa1The K_a_ upper statephys.atmol.qnintKc1The K_c_ upper statephys.atmol.qnintJ2The J lower statephys.atmol.qnintKc2The K_c_ lower statephys.atmol.qnintJ1The J upper statephys.atmol.qnintrecnoRecord number assigned by the VizieR team.
