Solvatochromism

  "id": "MLC-T-CHM-011019",
  "term": "Solvatochromism",
  "field": "Chemistry",
  "definition": "The phenomenon where the color or spectral properties (e.g., absorption or emission maxima) of a chemical compound change significantly with a change in the solvent. This effect arises from differential stabilization of the ground and excited electronic states by solvent-solute interactions. It is commonly observed in highly polar or charge-transfer compounds and is used to probe solvent polarity.",
