Abstract Ion mobility spectrometry (IMS) in combination with different techniques of atmospheric pressure ionization (63Ni ionization, photoionization, Corona discharge ionization) was applied to determine the influence of structural features of aromatic and cyclic hydrocarbons on ion mobility spectra. For this purpose, different sets of isomeric hydrocarbons were investigated using the above-mentioned ionization techniques. We found different structural features of these isomeric non-polar compounds which cause distinct differences in ion mobility spectra. These differences result from the formation of different product ions or a different relative abundance of ions formed depending on the occurrence of certain structural features (position of the double bond, arrangement of double bonds within the carbon ring, configuration of aliphatic side chain in the space, position of aliphatic side chain on the carbon ring and the number of carbon atoms in the aliphatic side chain). The nature of product ions formed was determined using a coupling of IMS with mass spectrometry (MS).
