摘要：
Tandem mass spectrometry has been used to differentiate positional isomers of some monoalkylated naphthalenes. The basis of the distinction is the cluster of peaks from m/z 150 to 155. Principal components analysis can extract isomer-specific information that is not obvious from simple visual inspection of the spectra. The analysis led to the observation of similar trends in single-stage electron impact mass spectra.
