  "id": "MLC-T-CHM-010256",
  "term": "Resonance radiation",
  "field": "Chemistry",
  "definition": "Electromagnetic radiation that is absorbed by an atom or molecule, causing it to transition from its ground electronic state to an excited electronic state, and is then re-emitted at the same wavelength as the absorbed radiation. This process is a form of fluorescence where no energy is lost to vibrational relaxation. It is characteristic of atomic species and some simple molecules.",
