  "term": "Resonance line",
  "field": "Chemistry",
  "definition": "A spectral line corresponding to a transition between the ground electronic state and the lowest excited electronic state of an atom or molecule. This transition involves the absorption or emission of a photon. The resonance line is typically the strongest spectral line observed in atomic spectroscopy.",
