cds-question@unistra.fratomic-physicsradio-spectroscopySince interstellar detection of propenal is only based on two rotational transitions in the centimeter wave region, its high resolution rotational spectrum has been measured up to 660GHz and fully characterized by assignment of more than 12000 transitions to provide direct laboratory data to the astronomical community. Spectral assignments and analysis include transitions from the ground state of the trans and cis isomers, three trans-^13^C isotopologues, and ten excited vibrational states of the trans form. Combining new millimeter and submillimeter data with those from the far-infrared region has yielded the most precise set of spectroscopic constants of trans-propenal obtained to date. Newly determined rotational constants, centrifugal distortion constants, vibrational energies, and Coriolis and Fermi interaction constants are given with high accuracy and were used to predict transition frequencies and intensities over a wide frequency range. Results of this work should facilitate astronomers further observation of propenal in the interstellar medium.2015ApJS..218...30Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/218/30CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/572/A44 : Vibrationally excited vinyl cyanide in Orion-KL (Lopez+, 2014)J/ApJ/768/81 : Ethyl cyanide, CH_3_CH_2_CN, vibrational states (Daly+, 2013)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/218/30https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/218/30http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/218/30https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/218/30https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/218/30http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/218/30GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapRadiodefaultJ/ApJS/218/30/table2Laboratory assigned and fitted transition frequencies for the trans-propenal parent, trans-13C-species, cis-propenal ground states and ten excited vibrational states of trans-propenalRefData source (1)meta.bibintrecnoRecord number assigned by the VizieR team.
