... ppm). The benzene dimer is the simplest prototype of the aromatic p–p interactions which is an important weak interaction present in aromatic supramolecular systems [12]. Since the number of ... picture for these electors is very similar (see Fig. 3), we may expect that the strength of the aromatic aromatic interac- tion in a borozene dimer is comparable to that of the benzene dimer. To...

... of B 60 H 12 . In order to estimate the degree of aromaticity, the calculation of Nuclear Independent Chemical Shifts [27] on the plane of the aromatic system (NICS0) was computed using the Gaussian ... level. Now we turn to aromaticity which, as already men- tioned, is considered as the basis of stability for boron planar clusters. Szwacki et al. [15] have discussed about the regions of ar...
