		| Abstract: | 
		The chemical composition and carbon isotope ratio of the bright, giant 
 star YY Psc (M3 III) are investigated from high resolution, high 
 signal-to-noise spectra obtained with the ESO VLT/CRIRES 
 instrument. The high-quality, sharp-lined spectrum was obtained as
 part of the ongoing CRIRES–POP observing program. The spectrum 
 was analyzed using synthetic spectrum techniques, and a preliminary 
 analysis shows that the 12C/13C ratio is ∼ 10 
 and the iron abundance is consistent with the solar value. |
