A simple chemical model for the electron polarization of cyclopentyl radicals produced in radiolysis

The electron polarization of cyclopentyl radicals was observed by Smaller . This paper presents an attempt to account for this observation by an initial polarization mechanism. The mechanism is based on the addition of hydrogen atoms to the product olefin to give the alkyl radicals. The electron polarization of the alkyl radicals arises from the polarized hydrogen atoms. It should be emphasized that the processes leading to polarized H atoms are not established but it is assumed that they are formed initially with the populations in αa_eα_N and α_eβ_N being greater than β_eα_N and β_eβ_N, respectively.
