Phase cycling

{
  "id": "MLC-T-CHM-008733",
  "term": "Phase cycling",
  "field": "Chemistry",
  "definition": "A technique in pulsed nuclear magnetic resonance spectroscopy where the phases of radiofrequency pulses and receiver detection are systematically varied in a sequence. This method is applied to suppress unwanted signals, such as those arising from instrumental imperfections or specific coherence pathways. A common phase cycle involves a four-step sequence to eliminate quadrature images and DC offsets.",
