cds-question@unistra.fratomic-physicsIt has long been suggested that CH_2_CN^-^ (cyanomethyl anion) might be a carrier of one of the many poorly characterized diffuse interstellar bands. In this paper, our aim is to study various forms (ionic, neutral, and deuterated isotopomer) of CH_2_CN (cyanomethyl radical) in the interstellar medium. The aim of this paper is to predict spectroscopic characteristics of various forms of CH_2_CN and its deuterated derivatives. Moreover, we would like to model the interstellar chemistry for predicting the column densities of such species around dark cloud conditions.2014A&A...562A..56Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/562/A56CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/562/A56https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/562/A56http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/562/A56https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/562/A56https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/562/A56http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/562/A56GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/A+A/562/A56/tableb1Vibrational frequencies of different forms of CH_2_CN in gas phase and water ice at B3LYP/6-311G++ levelrecnoRecord number assigned by the VizieR team.
