Spin polarization transfer during the addition reaction of phosphorus radicals to simple olefins in solution.

A CIDEP study of the radical adducts formed by addition of phosphonyl radicals to several unsaturated organic compounds is described. The complicated time-resolved ESR spectra obtained for these adducts were interpreted on the basis of competing chemical and physical processes involved in polarization transfer to the secondary radicals produced. This is a novel example illustrating for the first time radical pair polarization transfer in solution. [ABSTRACT FROM AUTHOR]
