The molecular weight of a compound is typically indicated by the heaviest peak on a mass spectrum, which i presumed to correspond to the molecular ion (M*). For smaller compounds, the heaviest peak tends to also be the most intense peak. The lighter peaks in the spectrum result from fragmentation of the molecule into smaller ions. Since peak intensity correlates to the relative stability of the ions produced, the peaks of the ionized fragments can be more intense than the...
