S. ; Lambert, D. L. Abstract Observations of stellar spectra at a resolution of 0.2 A support the identification of FeH and CeO in S stars by resolving the rotational structure of the bands. FeH lines are also identified in 61 Cyg B (K5 V), Alpha Tau (K5 III), and in two M giants. CeO is present in the pure S star R Gem and in R And, an S star with TiO. The possibility of measuring Fe and Ce isotope ratios is discussed.
