One-photon photochromism

  "id": "MLC-T-CHM-008238",
  "term": "One-photon photochromism",
  "field": "Chemistry",
  "definition": "The reversible transformation of a chemical species between two forms with different absorption spectra, induced by the absorption of a single photon of light. This process involves a change in molecular structure, such as isomerization or bond cleavage, which can be reversed by light of a different wavelength or by thermal means. Many spiropyran and diarylethene compounds exhibit one-photon photochromism.",
