Gradient‐Enhanced One‐Dimensional Heteronuclear NOE Experiment with 1H Detection

A new experiment, HETGOESY, is described in which 13C–1H NOE enhancements are detected directly on 1H. The experiment uses pulsed field gradients for coherence selection, thus completely avoiding the problems associated with difference spectroscopy. It is shown, both theoretically and experimentally, that the new experiment has sensitivity advantages over the conventional 13C{1H} steady‐state NOE difference experiment. The new experiment also has the advantage that it uses selective excitation in the generally better resolved decoupled 13C spectrum rather than the 1H spectrum.
