  "term": "Spin polarization",
  "field": "Chemistry",
  "definition": "The phenomenon where the electron spins in a molecule or radical are not randomly oriented but exhibit a preferred alignment, often induced by the presence of unpaired electrons. This effect influences the magnetic properties and reactivity of chemical species. It is observed in electron paramagnetic resonance (EPR) spectroscopy.",
