Twelve positional isomers of tetradecenol were analysed by conventional combined gas chromatography/mass Spectrometry without any chemical derivatization for the elucidation of the double‐bond position. The spectra were interpreted in terms of similarity of mass spectral patterns based on a fuzzy reasoning method, in which the relative abundances of selected predominant fragment ions were chosen as standard parameters and similarity indices were devised. The method was tested with pure alcohols and enabled the double‐bond position to be located with acceptable accuracy.
