    • When an electron and a proton are transferred in a single step, there are also two mechanisms: hydrogen atom transfer and proton-coupled electron transfer. The precise definition of proton-coupled electron transfer has yet to be widely accepted, but this term is often applied to mechanisms in which the proton and electron are transferred between different sets of orbitals. See: Cukier, R. I.; Nocera, D. G. Annu. Rev. Phys. Chem. 1998, 49, 337.

    • The larger g value of cumylperoxyl radical than the free spin value (2.0023) is ascribed to the spin-orbit coupling interaction on oxygen atom, which has a large spin-orbit coupling constant. The charge-transfer interaction of cumylperoxyl radical with electron donors results in a decrease in the spin density on oxygen, which causes the decrease in the g value (S8).
