A new formula was presented for locating double bond position in dodecenols, tetradecenols, hexadecenols and their acetates, based on mass spectral data of dimethyl disulfide derivatives. In this procedure, molecular ion and base peak ion were utilized as characteristic parameters to identify the positional isomers. The method was tested with mass spectra of 25 dimethyl disulfide derivatives of mono‐unsaturated acetates and alcohols, and the original double‐bond position in each isomer was located unambiguously.
