Detailed Description

The Balaban index J is topological index.

It is calculated using the distance matrix with weighted edges of the molecular graph: 1 for single bonds, ${1}{2}$ for double bonds, ${1}{3}$ for triple bonds and ${2}{3}$ for aromatic bonds. \( J = {q}{(q-n+2)} {{adjac.}i,j} (s_i,s_j)^{-{1}{2}} \), $s_i$ and $s_j$ denotes the row sum of the distance matrix of atom $i$ and $j$.
