cds-question@unistra.fratomic-physicsspectroscopyWe present new, accurate predictions for rotational line positions, excitation energies, and transition probabilities of the ^12^C^13^C isotopologue Swan d^3^{Pi}-a^3^{Pi} system 0-0, 0-1, 0-2, 1-0, 1-1, 1-2, 2-0, 2-1, and 2-2 vibrational bands. The line positions and energy levels were predicted through new analyses of published laboratory data for the ^12^C^13^C lines. Transition probabilities were derived from recent computations of transition dipole moments and related quantities. The ^12^C^13^C line data were combined with similar data for ^12^C_2_, reported in a companion paper (2013JQSRT.124...11B), and applied to produce synthetic spectra of carbon-rich metal-poor stars that have strong C_2_ Swan bands. The matches between synthesized and observed spectra were used to estimate band head positions for a few of the ^12^C^13^C vibrational bands and to verify that the new computed line data match observed spectra. The much weaker C_2_ lines of the bright red giant Arcturus were also synthesized in the band head regions.2014ApJS..211....5Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/211/5CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/ApJS/210/23 : Line intensities of CN transitions (Brooke+, 2014)J/ApJS/207/26 : MgH in the A^2^{Pi}-X^2^{Sigma}^+^ system (Hinkle+, 2013)J/ApJ/747/102 : ^12^C/^13^C ratio for 18 galactic R CrB stars (Hema+, 2012)J/ApJS/194/34 : FT emission spectroscopy of ^13^C^14^N (Ram+, 2011)J/ApJS/182/80 : Rare earth abundances (Sneden+, 2009)J/ApJS/169/472 : Swan system of C2 (Tanabashi+, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/211/5https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/211/5http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/211/5https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/211/5https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/211/5http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/211/5GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/ApJS/211/5/table4Assignments, wavenumbers, excitation energies, and transition probabilities of individual ^12^C^13^C transitionsp'[ef] Upper state parityphys.atmol.paritycharp''[ef] Lower state parityphys.atmol.paritycharrecnoRecord number assigned by the VizieR team.
