Scientific paper

High-resolution infrared (4100-4500/cm) spectra of the SMR giants Alpha Ser and Tau Dra and eight other giants are analyzed to obtain the C-12/C-13 and O-16/O-17/O-18 ratios from the CO vibration-rotation first-overtone bands. It is shown that the lower limits to the O-16/0-17 ratios together with published estimates for Alpha Ser and Mu Leo are consistent with predictions for giants after the first dredge-up.
