title: On the use of organic extraction in the spin-trapping technique as applied to biological systems.
abstract: A back-extraction methodology is presented which involves extraction of a spin adduct from an organic medium into an aqueous medium where its spectral parameters are well established. This technique should prove very useful in properly identifying spin adducts formed in organic media. Some of the hazards of extracting spin adducts into organic solvents for study are pointed out.
