Biphotonic process

{
  "id": "MLC-T-CHM-001340",
  "term": "Biphotonic process",
  "field": "Chemistry",
  "definition": "A photochemical process that involves the absorption of two photons by a molecule to initiate a chemical or physical change. This can occur through simultaneous absorption (two-photon absorption) or sequential absorption via an intermediate excited state. Such processes are often used in microscopy and photodynamic therapy.",
