• Electron ionization mass spectra of substituted benzyl acetates [1] - [12] are measured. In general, the spectrum consists of four peaks: M+, [M-42]+, [M-59]+, and <I>m/z</I> 43 peak. A good Bursey-McLafferty correlation between log ([<I>m/z</I> 43]/[M]) and Hammett σ constants is found. The Einolf-Munson treatment of <I>m/z</I> 43 and [M-42] ions also gives an expected result. On the other hand, compounds [5] and [7] deviate considerably from the plott of log ([M-42]/[M]) vs. σ, and the Chin-Harrison analysis is applied to explain this discrepancy.
