Current laboratory spectra do not fully resolve the CO_2_ ice features. To improve the fitting of the observed CO_2_ features, high-resolution solid-state infrared spectra of pure CO_2_ ice are recorded in the laboratory for a series of astronomically relevant temperatures and at an unprecedented level of detail. The infrared spectra of pure CO_2_ ice were recorded in the 4000 to 400cm^-1^ (2.5-25um) region at a resolution of 0.1cm^-1^ using Fourier transform infrared spectroscopy. Accurate band positions and band widths (FWHM) of pure CO_2_ ice are presented for temperatures of 15, 30, 45, 60, and 75K. The focus of this spectroscopic work is on the CO_2_ (v2) bending mode, but more accurate data are also reported for the ^12^CO_2_ and ^13^CO_2_ (v3) stretching mode, and CO_2_ (v1+v3) and (2v2+v3) combination bands.2013A&A...555A..85Ihttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/555/A85CatalogResearchIsServedByTAP VizieR generic servicerelated-toVI/111 : ISO Observation Log (ISO Data Centre, 2004)J/A+A/390/1033 : The ISO-SWS post-helium atlas (Vandenbussche+, 2002)J/ApJ/743/131 : Interstellar water ice formation (Smith+, 2011)J/ApJS/86/713 : IR spectroscopy of ices (Hudgins+, 1993)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/555/A85https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/555/A85http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/555/A85https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/555/A85https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/555/A85http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/555/A85GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapInfrareddefaultJ/A+A/555/A85/listList of spectrarecnoRecord number assigned by the VizieR team.
