Abstract
The topological index epsilon recently proposed by one of the authors
[E. Estrada, J. Chem. Inf. Comput. Sci. 1995, 35, 31-33] is shown to b
e identical to the connectivity index of the line graph of the molecul
ar graph. This observation makes it possible to conceive a whole class
of novel, line-graph-based topological indices. The Wiener index prov
ides an exception: in the case of acyclic molecules, the Wiener index
of the molecular graph and the Weiner index of the line graph differ b
y a constant.
