Pure shift yielded by chirp excitation

{
  "id": "MLC-T-CHM-009682",
  "term": "Pure shift yielded by chirp excitation",
  "field": "Chemistry",
  "definition": "A method in nuclear magnetic resonance (NMR) spectroscopy that separates chemical shift information from spin-spin coupling interactions. This is achieved by applying a frequency-swept (chirp) pulse during the acquisition of the free induction decay. The resulting spectra display simplified signals, often appearing as single lines for each chemically distinct nucleus.",
