When FT-NMR is used to collect data without a sufficient delay time between subsequent pulses, the integrated area under certain peaks may result in a lower value than should be observed under appropriate conditions. This discrepancy in integration may deceive the inexperienced eye and consequently can lead to a wrong assignment of the NMR spectrum. The following exercise is designed to raise awareness of this issue in students and to serve as an inquiry-based stepping-stone into basic FT-NMR. The exercise can be conducted as part of an organic lab where the students are synthesizing a compound and analyzing its spectrum or as a theoretical exercise using the provided spectra.
