In that work, it was found that the quadrupole of the ring atoms, ∑ 𝑄 ' (𝐶), a measure of electronic delocalization (aromaticity) of the ring atoms affected by substituent effects, and the total charge of the nitro groups, ∑ 𝑄 # (𝑁𝑂 ' ), a measure of charge localization on the explosophore moiety, were the most important features affecting the prediction of ℎ .# . This conclusion was based on the good correlation (adjusted 𝑅 ' values greater than 0.90) of the models. However, the contribution weight of each property to the prediction of ℎ .# could not be quantified in that work. In contrast,
