Double-quantum filtered correlation spectroscopy

{
  "id": "MLC-T-CHM-003416",
  "term": "Double-quantum filtered correlation spectroscopy",
  "field": "Chemistry",
  "definition": "A nuclear magnetic resonance (NMR) technique that selectively detects signals arising from coupled spin systems that have undergone a double-quantum coherence transfer. This method suppresses signals from uncoupled spins and single-quantum coherences, simplifying complex spectra. It is particularly effective for identifying coupled protons in organic molecules.",
