Özet
New red and violet system line lists for the CN isotopologues 13 C 14 N and 12 C 15 N have been generated. These new transition data are combined with those previously derived for 12 C 14 N, and applied to the determination of CNO abundances in the solar photosphere and in four red giant stars: Arcturus, the bright, very low-metallicity star HD 122563, and the carbon-enhanced metal-poor stars HD 196944 and HD 201626. When both red and violet system lines are detectable in a star, their derived N abundances are in good agreement. The mean N abundances determined in this work are also generally in accord with published values.
