Interpreting the fragmentation pattern of the mass spectrum of propylbenzene [M]+ is the molecular ion peak (M) with an m/z of 120 corresponding to [C9H12]+, the original propylbenzene molecule minus an electron, [C6H5CH2CH2CH3]+. The small M+1 peak at m/z 121, corresponds to an ionised propylbenzene molecule with one 13C atom in it i.e. an ionised propylbenzene molecule of formula 13C12C8H12 Identifying the species giving the most prominent peaks (apart from M) in the fragmentation pattern of propylbenzene.
