Nuclear Overhauser effect

{
  "id": "MLC-T-CHM-008109",
  "term": "Nuclear Overhauser effect",
  "field": "Chemistry",
  "definition": "A change in the intensity of a nuclear magnetic resonance (NMR) signal of one nucleus when the NMR signal of a nearby nucleus is saturated by radiofrequency irradiation. This effect arises from through-space dipole-dipole interactions between nuclei and is highly dependent on the distance between them. It is a powerful tool for determining internuclear distances and molecular conformation.",
