The thermal and photolytic behavior of diazoketones has received much attention because of the variety of reactions they undergo. 2 Correlation between thermal and photolytic reactions and reactions induced by electron impact 3 made a study of the inass spectral fragmentation of diazoketones of

## Abstract The electron impact mass spectra of 1βphenylβ2βpropenβ1βol and its specifically deuterated analogues have been investigated. Most of the decomposition pathways involve skeletal rearrangements or hydrogen atom transfers, such that a rearrangement of the excited molecular ions of 1βphenyl
## Abstract The 70 eV electron impact mass spectra of six 2βaminooxazoles are discussed in detail with the aid of exact mass measurements, metastable ion detection in the defocused mode and labelling experiments. The fragmentation is markedly influenced by strong electron donating substituents at t
## Abstract 1,1β²βBicycloalkylβ2,2β²βdiols (mixtures of stereoisomers) and 1,1β²βdiols on electron impact give rise to strong peaks equivalent to [Mβ1]^+^ions, corresponding to cycloalkenone fragments and obviously involving hydrogen atom migrations. Deuterium labelling and substitution techniques rev
