steady-state nuclear Overhauser enhancement spectroscopy steady state nOesy A type of heteronuclear NMR spectroscopy where a second frequency dimension is employed, based on the nuclear Overhauser enhancement effect in which correlations are seen between nuclei that are spatially proximate within a molecule (<=6 \AA apart). In this technique, the saturation of a particular proton resonance (signal) perturbs the intensities of signals from spatially proximate nuclei. steady-state nuclear Overhauser enhancement spectrometry CHMO:0000611 steady-state NOESY steady state NOESY steady-state nOesy two-dimensional nuclear Overhauser enhancement spectroscopy
