Abstract
Electron impactโinduced fragmentations of isomeric dodecenโ1โols were investigated using massโanalysed ion kinetic energy (MIKE) spectrometry and highโresolution data. The principal fragmentation pathways of the positional isomers studied are dominated by the C๏ฃพC double bond and involve migration and radicalโsite rearrangements along the carbon chain with the aid of consecutive rearrangements of hydrogen atoms.

Characteristics of mass spectra of isomeric tetradecadien-1-ols were investigated by electron impact mass spectrometry, and mass spectral fragmentation pathways were proposed based on collision-induced dissociation experiments and mass-analyzed ion kinetic energy spectrometry.
Propranolol, its 1@-mono-, di-, and trifluorinated analogs, and other related compounds were analyzed under electrospray ionization ion trap collision-induced dissociation (ESI-CID) and electron impact (EI) conditions. Interesting trends were observed in the fragment ions formed in both cases. Under
