title: A new approach for EPR detection of hydroxyl radicals by reaction with sterically hindered cyclic amines and oxygen.
abstract: Sterically hindered cyclic amines react with hydroxyl radicals in the presence of oxygen to yield stable nitroxide radicals which can be detected by EPR. This reaction provides a nonconventional spin-trapping tool for detection of hydroxyl radicals.
