Metastable Ion Studies. V. The Identification of C2H4O+ Ion Structures from their Characteristic Kinetic Energy Releases

Metastable ion peaks for the fragmentation C 2 H 4 O + • → C 2 H 3 O + + H • have been studied in the first field-free region of a double focussing mass spectrometer under conditions of good energy resolution. Three isomeric C 2 H 4 O + • ions were generated[Formula: see text] (b) CH 3 CHO + , and (c) CH 2 =CHOH + • from ethylene oxide, acetaldehyde, and ethyl vinyl ether respectively, each fragment producing a different 1 m* peak having a …
