The absolute photoionization cross‐sections of aromatics and aromatic derivatives including toluene, ethylbenzene, n ‐propylbenzene, o ‐xylene, m ‐xylene, p ‐xylene, 1,3,5‐trimethylbenzene, styrene, phenylacetylene, indene, indane, 1‐methylnaphthalene, benzyl alcohol and benzaldehyde were measured at the photon energy range from ionization thresholds to 11.7 eV. The experiments were performed by tunable synchrotron vacuum ultraviolet (VUV) photoionization mass spectrometry. Benzene was chosen as a calibration standard, since its photoionization cross‐section is well known. Binary liquid mixtures of the investigated molecules and benzene were used in the measurements. Photo‐induced fragments from the molecules were also observed, and their photoionization cross‐sections are also presented. Copyright © 2009 John Wiley & Sons, Ltd.
