Abstract

The fragmentation of 15 alkyl 1‐methylpyridinium ether derivatives (D^+^) of primary and secondary alcohols, benzylic alcohols and phenyl‐substituted alcohols was investigated using energy‐resolved tandem mass spectrometry. Fragmentation pathways and mechanisms, including the influence of substituents, on the formation of the major product ions, which appear at m/z 110, [D − 109]^+^ and [D − 111]^+^, were postulated. Comparison of the abundances of these ions in the product ion spectra of isomeric alcohol derivatives, obtained at the same center‐of‐mass collision energy (2.0 eV), was found to provide the ability to differentiate among some isomers.
