The mass spectrometric fragmentation behavior of the cyclic hexafluoroacetone ketals derived from eighteen n ‐alkenes is discussed with emphasis on locating the original olefinic bond. The major analytically useful fragments result from loss of CF 3 , loss of an alkyl side chain or loss of an aldehyde moiety from the ring. Influences of geometric isomerism on the spectra are examined by intensity ratios and ratios of competing fragmentations.
