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