anti-Stokes type radiation

  "id": "MLC-T-CHM-000714",
  "term": "anti-Stokes type radiation",
  "field": "Chemistry",
  "definition": "Electromagnetic radiation emitted by a substance at a higher frequency (shorter wavelength) than the exciting radiation. This phenomenon occurs when the absorbing species is already in an excited state and transitions to a lower energy state, releasing energy in excess of the absorbed photon's energy. It is less common than Stokes type radiation, where the emitted light has a lower frequency than the absorbed light.",
