NO+ chem.-ionization mass spectrometry is a highly efficient tool for locating the C:C double bond in long-chain monounsaturated alcs., acetates, and aldehydes Me(CH2)xCH:CH(CH2)yR (R = CH2OH, CH2OAc, CHO). The double bond assignment is mostly provided by the presence of an acylium ion Cx+2H2x+3O+ formed from the alkyl side of the mol. When the double bond is close to the terminal oxygen function (y ≤ 2), a Cy+3H2y+4NO+ ion may also be used as a complementary diagnostic ion. In the case of di- or triethylenic compounds, an acylium ion is also formed which characterizes the external (unconjugated) double-bond position. From the observed strong influence of the sample pressure on the formation of the acylium ion and results of MS/MS experiments, two mechanisms are proposed to explain the origin of this diagnostic ion. Although some instrument dependence may not be excluded, the method is optimally applicable to moderate sample loads (20-200 ng).
