Mass spectra of some acyclic α,β‐unsaturated aldehydes, ketones and esters

Abstract
The mass spectra of a series of aliphatic acyclic α,β‐unsturated aldehydes, ketones and ester have been examined. The spectra do not show evidence for McLafferty rearrangements, alkoxyl migration or for fragmentations which are dependent upon the s‐trans or s‐cis conformations of the compounds. There is some evidence for cistrans isomerism about the double bond.
