Spin trapping chemistry of 3,3,5,5-tetramethylpyrroline-N-oxide: an improved cyclic spin trap

Abstract

The use of 3,3,5,5-tetramethylpyrroline-N-oxide as a spin trap has been investigated. Spin adducts are found to be more persistent than for 5,5-dimethylpyrroline-N-oxide (DMPO) although the esr spectra are quite similar.
