Abstract

We can envision two applications of this experimental approach. First, the identification of isomeric ions (or their neutral precursors) which give nearly identical E1 or collision-induced decomposition spectra (such as C8H8 isomers) can be accomplished by" derivatizing" the ion or neutral in a high-pressure source followed by analysis using MS/MS.% For example, we anticipate that of the isomeric
