| Abstract: | Collisionally activated dissociation (CAD) mass spectra sometimes appear to be identical in spite of the fact that the precursor ion structures are known to differ. It is shown that determination of the experimental overall cross-section for collisionally activated decomposition yields valuable extra information. After applying it to examples of known structure, C4H5N]+·, C5H5N]+· and C5H5O]+, it is used to study a more complex problem, that of C6H6]+· ions from four isomeric precursors. |
