Zero-field nuclear magnetic resonance spectroscopy

  "id": "MLC-T-CHM-012802",
  "term": "Zero-field nuclear magnetic resonance spectroscopy",
  "field": "Chemistry",
  "definition": "A variant of nuclear magnetic resonance spectroscopy in which spectra are acquired in an environment screened from magnetic fields, including the Earth's field, so that the spins evolve without Zeeman interactions. The spectra show J-coupling splittings directly, known as J-spectra, and the line widths do not depend on the homogeneity of an applied field. Signals are commonly detected with atomic magnetometers or SQUID sensors.",
