Abstract
The mass spectra of fifteen members of the alpha and beta substituted naphthylthiaalkanes with a molecular weight range of 202 to 300 are reported. The data areused to illustrate the process of correlation and delineation of fragmentation routes in a class of compounds to benefit mass spectroscopists. Spectra from low, medium, and high resolution instruments are employed, showing the necessity and usefulness of multiple approaches in obtaining a complete understanding of the pathways involved. Application of low ionization voltage, metastable ion data, doubly charged ions, and high resolution mass spectrometry is described to arrive at an outline of the major fragmentation routes in a given class of compounds. For unknown compounds in their class, the analyst can readily make an identification from the predicted mass spectrum by utilizing this information.
