α-Tocopherol impact on oxy-radical induced free radical decomposition of DMSO: Spin trapping EPR and theoretical studies

► α-Tocopherol does not inhibit the oxidation of DMSO to
- CH3. ► α-Tocopherol inhibits the oxidation of
- CH3 to
- OCH3. ► α-Tocopherol does not inhibit the oxidation of PBN. ► The structures of observed spin adducts were theoretically confirmed.
