radical pair
- any two radicals (def. 1) in close proximity in liquid solution, with a solvent cage. They may have been formed simultaneously, e.g. by homolysis, or have come together by diffusion. Whilst together, correlation of their unpaired electron spins occurs and manifests itself as a distortion of nuclear magnetic resonance spectra.
- a cation and anion radical produced transiently in the primary photochemical process of photosynthesis. See photosystem.
