Interpretation Of Mass SpectraInterpretation 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. "Prof. McLafferty's text has become a classic for classroom or self study concerned with interpreting mass spectra in order to discern molecular structures or identities of compounds."
