Improved line data for the Swan system ^12^C^13^C
Listed in IVOA Registry (Virtual Observatory)
We 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.
Description
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.
