Gradient-selected heteronuclear multiple quantum coherence

Definition: A type of heteronuclear NMR spectroscopy where a second frequency dimension is employed to disperse the signals and reveal correlations between protons and the nuclei to which they are covalently bound. A spatially inhomogeneous magnetic field is applied with a defined gradient and used to either select a particular signal or to render unwanted signals undetectable.
