Nuclear magnetic resonance spectroscopy experiment designed to show homonuclear spin-spin coupling correlations between low natural abundance nuclei such as \(\ce{^{13}C}\).
Note: 2D variant shows each coupled pair of nuclei gives a pair of peaks on the INADEQUATE spectrum which both have the same vertical coordinate, which is the sum of the chemical shifts of the nuclei; the horizontal coordinate of each peak is the chemical shift for each of the nuclei separately.
