A new method for locating double bonds in olefins and fatty acid is described. The CCI 2 moiety, derived form chloroform, was added across the double bonds of a series of compounds using a phase‐transfer reaction. The resulting adducts were then analysed by gas chromatography/positive‐ion electron ionization mass spectrometry. It was found that it is routinely possible to locate a single double bond in a molecule at the microgram level. The method proved, however, to be of no use in locating terminal double bonds or in distinguishing geometrical isomers. It is possible that the method might be extended to di‐olefins.
