Quantitative [superscript 13]C NMR provides a straightforward method of analyzing edible oils in undergraduate chemistry laboratories. [superscript 13]C spectra are relatively easy to understand, and are much simpler to analyze and workup than corresponding [superscript 1]H spectra. Average chain length, degree of saturation, and average polyunsaturated fatty acid content of common edible oils are obtained directly using integrals of the proper regions in the [superscript 13]C 1D spectra. These spectra segue to 2D [superscript 1]H - [superscript 13]C HSQC experiments that provide an excellent path for students to verify assignments, in particular those associated with polyunsaturated fatty acids. Data acquisition and analysis can be completed in one to two lab sections, although spectrometer scheduling may be necessary for groups of students greater than six. [superscript 13]C relaxation measurements of common oils are presented that enable accurate quantitative [superscript 13]C data to be obtained in reasonable amounts of time (30-40 min per sample) on modern 400 MHz NMR spectrometers.
