Outer-sphere electron transfer

{
  "id": "MLC-T-CHM-008370",
  "term": "Outer-sphere electron transfer",
  "field": "Chemistry",
  "definition": "A mechanism of electron transfer between two chemical species where the electron moves directly from the donor to the acceptor without any direct bond formation or breaking between them. The coordination spheres of the reactants remain intact during the electron transfer event. This process is often described by Marcus theory, which considers the reorganization energy of the solvent and reactants.",
