Key Concepts at a Glance
- Inner Sphere Mechanism — Electron transfer via a bridging ligand shared between donor and acceptor complexes.
- Outer Sphere Mechanism — Electron transfer between complexes with intact coordination spheres — no bridging ligand.
- Marcus Theory — Quantitative framework relating activation energy to driving force and reorganisation energy.
- Complementary Reactions — Reactions where both oxidation states change by the same amount — one-electron vs two-electron transfer.
