Other magnetic probes of aromaticity e.g. NICS

Interrelations between the Geometric, Energetic and Magnetic Criteria 

The extensive literature on aromaticity reveals a significant degree of confusion and controversy regarding the assessment of aromaticity using the above-mentioned criteria and regarding the correlation between them. The examples below demonstrate the current 

In view of the above-mentioned controversy about the definition of aromaticity, it is obvious that there is no unique way to quantify the degree of aromaticity of a particular compound and that any quantification of aromaticity is likely to be highly controversial. Keeping in mind the above discussion on the nature and definition of aromaticity we now examine the available theoretical studies of silaaromatic and silaantiaromatic compounds.
