Abstract

This paper presents low and high resolution mass spectra as well as fragmentation processes under electron impact for methyl, ethyl and propyl‐pivaloyl acetate. The fragmentation patterns have been established using elemental compositions of ions determined by high resolution, metastable transitions and deuterium labelling.

The mass spectra of the C, to C, n-alkanals and a number of branched aldehydes have been obtained at a resolution sufficient to resolve the O-CH4 doublets. From the resolved spectra, a study of metastable transitions, and the spectrum of one deuterium-labelled alkanal, (n-hexanal-2,2-dz) the major f
