The electron impact (EI) mass spectral analysis of the picolinyl esters of nine positional isomers of conjugated diacetylenic fatty acids showed prominent M + and [M-l] + peaks. In all cases there was a regular series of ions 14 amu apart in the high molecular weight range until the triple bond syst
Picolinyl ester derivatives have proved to be of great value for the mass spectrometric location of double bonds in fatty acids. Their utility for the identification of triple bonds in a series of dimethylene-interrupted octadecadiynoic acids has now been investigated. In the electron-impact mass sp
