cds-question@unistra.fratomic-physicsradio-spectroscopyWe report a detailed spectroscopic investigation of the interstellar aminoacetonitrile, a possible precursor molecule of glycine. Using a combination of Stark and frequency-modulation microwave and millimeter wave spectroscopies, we observed and analyzed the room-temperature rotational spectra of 29 excited states with energies up to 1000cm^-1^. We also observed the ^13^C isotopologues in the ground vibrational state in natural abundance (1.1%). The extensive data set of more than 2000 new rotational transitions will support further identifications of aminoacetonitrile in the interstellar medium.2017ApJS..229...26Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/229/26CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/ApJS/209/23 : Aminoacetonitrile transition frequencies (Motoki+, 2013)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/229/26https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/229/26http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/229/26https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/229/26https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/229/26http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/229/26GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapRadiodefaultJ/ApJS/229/26/table4List of the assigned and fitted transitions for 29 excited vibrational states of the parent species and ground state transitions of two ^13^C isotopologues of aminoacetonitrile (NH2-CH2-CN)SpeciesSpeciesmeta.notecharrecnoRecord number assigned by the VizieR team.
