Spin decoupling

  "id": "MLC-T-CHM-011200",
  "term": "Spin decoupling",
  "field": "Chemistry",
  "definition": "A technique in nuclear magnetic resonance (NMR) spectroscopy where the spin-spin coupling between specific nuclei is eliminated by applying a strong radiofrequency field at the resonance frequency of one of the coupled nuclei. This simplifies the NMR spectrum by collapsing multiplets into singlets. It is widely used to assign signals and determine molecular structure.",
