cds-question@unistra.fratomic-physicsThe high spectral resolution R~45000 provided by IGRINS (Immersion Grating INfrared Spectrometer) at MacDonald Observatory and R~100000 achieved by CRIRES (CRyogenic high-resolution InfraRed) Echelle Spectrograph) at VLT challenges the present knowledge of infrared spectra. We aim to predict the full infrared spectrum of molecular hydrogen at a comparable accuracy. We take advantage of the recent theoretical ab-initio studies on molecular hydrogen to compute both the electric quadrupole and magnetic dipole transitions taking place within the ground electronic molecular state of Hydrogen. We compute the full infrared spectrum of molecular hydrogen at an unprecedented accuracy and derive for the first time the emission probabilities including both electric quadrupole ({Delta}J=0, +/-2) and magnetic dipole transitions ({Delta}J=0) as well as the total radiative lifetime of each rovibrational state. Inclusion of magnetic dipole transitions increases the emission probabilities by factors of a few for highly excited rotational levels, which occur in the 3-20{mu} range.2019A&A...630A..58Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/630/A58CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/630/A58https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/630/A58http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/630/A58https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/630/A58https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/630/A58http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/630/A58GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/A+A/630/A58/table2List of all infrared transition of the X H2 rovibrational statesrecnoRecord number assigned by the VizieR team.
