On the Calculation of the Molecular Descriptor χ’/χ
Dejan Plavšić, Milan Šoškić, Nella Lerš · Journal of Chemical Information and Computer Sciences · 1998
The molecular descriptor χ’/χ was recently introduced by Randić. The explicit formula for calculation of the χ’/χ index is derived. The formula provides an easy method to calculate the χ’/χ index for any connected graph. The advantages of the formula over the algorithm proposed by Randić et al. are pointed out.
