“…Although the struc ture elucidation power of MS/MS is well documented (26,27), MS/MS can also be used to confirm the pres ence of proposed products of electro chemical reactions if standards are available. Such confirmation can be accomplished by comparing the pro duct spectra of authentic standards with those of electrochemically gen erated products (24)(25)(28)(29)(30)(31). Each compound produces a unique frag mentation pattern under MS/MS conditions that is characteristic of its structure, analogous to an IR finger print or an EI spectrum.…”
