Fig. A.3.


Summed 600–1700 cm−1 emission spectrum of the five pentagon containing cations in PAHdb with harbors (cf. Table 2). The bands have been convolved with a Gaussian line profile with a FWHM of 30 cm−1. The 1σ variation around the mean is indicated by the gray shaded area. The 9.3, 8.6 and 6.2 μm band positions have been indicated with the long-dashed lines. Straight-line continua used to isolate the 9.3 and 6.2 μm PAH bands are shown as dotted lines. See Sect. 4.3 for details.
