Photodesorption

{
  "id": "MLC-T-CHM-008842",
  "term": "Photodesorption",
  "field": "Chemistry",
  "definition": "The process by which molecules adsorbed on a surface are released into the gas phase upon illumination. This phenomenon occurs when absorbed photons provide sufficient energy to break the adsorbate-surface bond or induce electronic transitions that weaken the interaction. It is the reverse process of photoadsorption.",
