title: The synthesis and use of a (15)N and (2)H isotopically-labelled derivative of the spin-trap 3, 5-dibromo-4-nitrosobenzenesulphonic acid.
abstract: We report the synthesis and use of d2-(15)N isotopically-labelled 3, 5-dibromo-4-nitrosobenzenesulphonic acid (DBNBS-d2-(15)N, as its sodium salt), a spin-trap possessing several advantages over non-labelled DBNBS. The simplification in the electron paramagnetic resonance spectra of radical adducts of DBNBS-d2-(15)N compared with those of DBNBS not only results in increased sensitivity, but also facilitates the assignment and analysis of complex spectra. An example of this simplification is given.
