  "id": "MLC-T-CHM-010247",
  "term": "Resonance fluorescence",
  "field": "Chemistry",
  "definition": "The re-emission of radiation by an atom or molecule at the same wavelength as the absorbed radiation, following excitation to a higher electronic state. This process occurs when the excited state relaxes directly back to the ground state without any vibrational energy loss. It is a rapid process, typically occurring on the picosecond to nanosecond timescale.",
