A survey of 18 O isotope effects on 13 C chemical shifts shows that a linear relationship exists between the magnitude of the one‐bond isotope effect and the chemical shift of the carbon atom for carbonyl groups. No such correlation was found for functional groups in which the oxygen atoms are connected to the carbon atoms via single bonds.
