The resulting dissimilarity between the STM images and the corresponding aromaticity patterns, in sharp contrast to the benzenoid systems, is verified in Fig. . This, after so many years, answers the question of Gutman et al. about the relationship of aromaticity patterns and STM images in non-benzenoid systems. The answer is clearly negative. However, for benzenoid structures such comparison can reveal the true spin state of the system. SW4x2); and finally, for well-balanced sublattices the result is closed shell non-magnetic states (e.g. AGNRs). Finally, we can summarize (in a form of Decalogue) the specific key findings of the present work, as follows:
