Rotational echo double resonance

  "id": "MLC-T-CHM-010425",
  "term": "Rotational echo double resonance",
  "field": "Chemistry",
  "definition": "A solid-state nuclear magnetic resonance (NMR) technique that measures heteronuclear dipolar couplings between specific spin pairs. It employs magic angle spinning to average out anisotropic interactions while reintroducing the desired dipolar coupling with radiofrequency pulses. This method provides precise internuclear distance measurements, typically in the range of 0.2 to 0.6 nanometers.",
