investigated by spin trapping by using alpha}-phenyl N-tert-butyl nitrone (PBN) and 5,5-dimethylpyrroline N-oxide (DMPO). The aminoxyl products identified by ESR and mass spectroscopy (MS) are the results of trapping 2-cyano-2-propyl radicals (CPsup sm bullet}}) in the presence of oxygen. By low-temperature ESR the 2-cyano-2-propylperoxyl adduct or PBN-nitronyl-sup13}C is detectable in the presence
