Heteronuclear multiple bond correlation NMR

{
  "id": "MLC-T-CHM-005258",
  "term": "Heteronuclear multiple bond correlation NMR",
  "field": "Chemistry",
  "definition": "A two-dimensional nuclear magnetic resonance (NMR) experiment that correlates the chemical shifts of two different types of nuclei that are coupled over two or more bonds. This technique is particularly useful for establishing long-range connectivity in molecules. It provides information about carbon-proton coupling over two, three, or even four bonds.",
