  "field": "Chemistry",
  "definition": "A set of coupled differential equations that describe the time-dependent behavior of a nuclear spin's magnetization vector in the presence of a magnetic field. These phenomenological equations model the effects of precession, relaxation (T1 and T2), and radio-frequency pulses on the net magnetization. They form the classical basis for understanding and simulating most nuclear magnetic resonance (NMR) experiments.",
