cds-question@unistra.fratomic-physicsA comprehensive chemistry of the highly deuterated species D_2_, D^+^_2_, D_2_H^+^, and D^+^_3_ in the early universe is presented. Fractional abundances for each are calculated as a function of redshift z in the recombination era. The abundances of the isotopologues are found to display similar behavior. Fractionation enhances the abundances of most of the more highly deuterated species as the redshift decreases due to the closing of some reaction channels as the gas temperature cools. Rate coefficients for the majority of the reactions involving the deuterated species are uncertain resulting in a corresponding uncertainty in their predicted abundances.2011ApJ...737...44Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/737/44CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/547/A33 : Chemical reactions for a deuteration network (Vastel+, 2012)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/737/44https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/737/44http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/737/44https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/737/44https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/737/44http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/737/44GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/ApJ/737/44/table1Reaction rate coefficientsR1Reactant 1phys.atmol.elementcharR2Reactant 2phys.atmol.elementcharP1Product 1phys.atmol.elementcharP2Product 2phys.atmol.elementcharP3Product 3phys.atmol.elementcharrecnoRecord number assigned by the VizieR team.
