Interpretation of Mass Spectra, say the authors, "aims at correlating ion dissociation mechanisms on a much broader scale, with emphasis on basic attributes such as ionization energies, proton affinities, and bond dissociation energies". They stress that the most important part of learning how to interpret unknown mass spectra is to practise doing it.
