Interpreting the fragmentation pattern of the mass spectrum of E-pent-2-ene and Z-pent-2-ene The fragmentation patterns are quite similar so the following notes apply to both spectra. [M]+ is the molecular ion peak with an m/z of 70 corresponding to [C5H10]+, the original E-pent-2-ene and Z-pent-2-ene molecule minus an electron, [CH3CH2CH=CHCH3]+. The small M+1 peak at m/z 71, corresponds to an ionised E-pent-2-ene and Z-pent-2-ene molecule with one 13C atom in it i.e. an ionised E-pent-2-ene and Z-pent-2-ene molecule of formula 13C12C4H10 Identifying the species giving the most prominent peaks (apart from M) in the fragmentation pattern of E-pent-2-ene and Z-pent-2-ene.
