The feasibility of the application of selective 13 C{ 1 H} nuclear Overhauser effect (NOE) measurements to organic structural analysis in 13 C NMR spectroscopy has been investigated at 25 MHz using citraconic anhydride and the methyl ester of pentalenolactone as model compounds. This selective 13 C{ 1 H} NOE technique with single frequency low‐power 1 H irradiation should find wide application in the structural elucidation of organic compounds, especially for the reliable assignment of quaternary carbon signals.
