The principal fragmentation pathways of the molecular ions of 18 new ( E ) ‐ 4‐alkoxycarbonylalkylthiochalcones have been investigated. It has been shown that the data derived from electron ionization mass spectra (the relative abundance of the fragment ions and values of coefficients µ ) can be used to differentiate the isomers. The fragmentation rules deduced here could help in the characterization of other chalcones of these types. Copyright © 2008 John Wiley & Sons, Ltd.
