cds-question@unistra.fratomic-physicsradio-spectroscopyThe methoxy radical (CH_3_O) has recently been detected in the interstellar medium and may be an important tracer of methanol-related chemistry in cold sources. Despite its importance, the spectral information needed to guide further astronomical searches is limited. We have therefore studied the low-temperature rotational spectrum in the laboratory within the spectral range of 246-303GHz. We have combined these new measurements with results from a number of literature reports to refine the molecular parameters and provide an updated and improved spectral line catalog. We present here the results of the laboratory studies and the refined analysis for the millimeter and submillimeter spectrum of methoxy.2017ApJ...835...46Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/835/46CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/587/A130 : HCO and CH_3_O in prestellar cores (Bacmann+, 2016)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/835/46https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/835/46http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/835/46https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/835/46https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/835/46http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/835/46GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapRadiodefaultJ/ApJ/835/46/table3Assigned transitions for the ground state of methoxyN-l[0/6] N value of the lower statephys.atmol.qnintrecnoRecord number assigned by the VizieR team.
