as well as the anion show a clearly increase in intensities compared to the neutral molecule. The cations show a peak near the 6.2$\mu$m band, no matter if defected or not. But the typical bands at 7.7$\mu$m and 8.6$\mu$m cannot be found for our molecules. Only the defected form of coronene shows peaks near these bands. In general, for cations, neutrals and anions, the intensities of the defected molecules seem to exceed the results of the normal molecules. The positions of the lines are shifted in the defect state. The addition of defects leads to more bands than found in the normal molecules. For better comparison with the UIR bands, dashed lines are drawn at 6.2 $\mu$m, 6.9 $\mu$m, 7.7 $\mu$m and 8.6 $\mu$m.

In Fig. \[1015.fig\] the 10 - 15 $\mu$m region of the spectra is shown. The lines in this area originate from C-H out-of-plane bending motion. It is expected that the undefected molecules show bands near 11.2$\mu$m, wherein the peaks of the cations occur at shorter wavelengths, of the anions at longer wavelengths. Our spectra confirm this, even the molecules with defect follow this trend. We note that the differences between defected and defect-free molecules is not
