J-resolved spectroscopy

{
  "id": "MLC-T-CHM-006290",
  "term": "J-resolved spectroscopy",
  "field": "Chemistry",
  "definition": "A two-dimensional nuclear magnetic resonance (NMR) experiment that separates chemical shifts from spin-spin coupling constants (J-couplings) into orthogonal frequency axes. This technique provides a projection onto one axis that contains only chemical shift information, simplifying complex spectra. The resulting 2D spectrum typically displays chemical shift along one axis and J-coupling along the other.",
