cds-question@unistra.fratomic-physicsinterstellar-mediummillimeter-astronomysubmillimeter-astronomyAminoacetonitrile has been detected in the interstellar medium and the Strecker-type synthesis is considered as one of its possible mechanisms of formation in this medium. Methyleneaminoacetonitrile (CH_2_=N-CH_2_-CN, MAAN) is one of the by-products of the Strecker reaction and a good candidate for astrophysical detection. Rotational spectrum of MAAN has never been studied before. To provide the basis for the detection of MAAN in the interstellar medium we studied its millimeter and submillimeter-wave spectrum. The rotational spectrum of MAAN was measured in the frequency range 120-600GHz. The spectroscopic study was supported by theoretical calculations of the molecular structure and harmonic force field. The ground and two lowest excited vibrational states of the most stable synperiplanar conformation of MAAN were assigned and analyzed. Obtained sets of rotational constants allows us to make accurate predictions of transition frequencies of MAAN in the frequency range up to 900GHz.2013A&A...559A..44Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/559/A44CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/493/565 : Deuterated and ^15^N ethyl cyanides (Margules+, 2009)J/A+A/538/A51 : Rotational spectrum of CH_3_CH(NH_2_)CN (Mollendal+, 2012)J/A+A/538/A119 : Spectrum of ^18^O-methyl formate (HCO18OCH3) (Tercero+ 2012)J/A+A/540/A51 : Submm spectrum of deuterated glycolaldehydes (Bouchez+, 2012)J/A+A/543/A46 : Submillimeter spectrum of HCOOCD_2_H (Coudert+, 2012)J/A+A/543/A135 : New analysis of ^13^C-CH_3_CH_2_CN up to 1THz (Richard+, 2012)J/A+A/544/A82 : Rotational spectroscopy of diisocyanomethane (Motiyenko+, 2012J/A+A/548/A71 : Spectroscopy and ISM detection of formamide (Motiyenko+, 2012)J/A+A/549/A96 : The mm & sub-mm spectra of 13C-glycolaldehydes (Haykal+, 2013)J/A+A/549/A128 : Singly deuterated isotopologues of formamide (Kutsenko+, 2013)J/A+A/552/A117 : Mono-deuterated dimethyl ether (Richard+, 2013)J/A+A/553/A84 : (Sub)mm spectrum of deuterated methyl cyanides (Nguyen+, 2013)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/559/A44https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/559/A44http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/559/A44https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/559/A44https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/559/A44http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/559/A44GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapRadiodefaultJ/A+A/559/A44/table2Assigned rotational transitions of the ground and two lowest excited vibrational states of MAANrecnoRecord number assigned by the VizieR team.
