Gibbs energy of photoinduced electron transfer

{
  "id": "MLC-T-CHM-004878",
  "term": "Gibbs energy of photoinduced electron transfer",
  "field": "Chemistry",
  "definition": "The change in Gibbs energy associated with an electron transfer reaction initiated by light absorption. This thermodynamic quantity determines the spontaneity and direction of the electron transfer process. It is often calculated using the Rehm-Weller equation, which considers the redox potentials of the donor and acceptor, and the Coulombic interaction between the resulting radical ions.",
