On the definition and calculation of the molecular descriptor R'/R

The molecular descriptor R'/R was recently introduced by Randic in this journal [M. Randic, Chem. Phys. Lett. 211 (1993) 478]. The original definition of R'/R can be used for acyclic structures only. The definition is extended here in a way so as to be applicable to any structure. The explicit formula for calculation of the R'/R index derived. The formula provides an easy method to calculate the R'/R index for any connected structure. The advantages of the formula over algorithm proposed by Randic are pointed out.
