Charge separation

{
  "id": "MLC-T-CHM-001905",
  "term": "Charge separation",
  "field": "Chemistry",
  "definition": "The process by which an excited molecular entity undergoes a redistribution of electron density, leading to the formation of distinct positive and negative charge centers. This often occurs after photoexcitation, where an electron is transferred from a donor to an acceptor moiety. Charge separation is a fundamental step in photosynthesis and photovoltaic devices.",
  "subject": "Organic and Biomolecular Chemistry",
