Phototautomerisation

{
  "id": "MLC-T-CHM-008932",
  "term": "Phototautomerisation",
  "field": "Chemistry",
  "definition": "A light-induced interconversion between two tautomeric forms of a molecule. This process involves the migration of a hydrogen atom or proton, accompanied by a rearrangement of double bonds, which is triggered by the absorption of a photon. Phototautomerisation can lead to changes in the spectroscopic properties, reactivity, or biological activity of the molecule, and is often observed in heterocyclic compounds.",
