Multicenter Wiener indices and their applications
Abstract
The Wiener index W can be viewed as a molecular structure descriptor composed of increments representing interactions between pairs of atoms. A generalization of the W are the Steiner-Wiener indices kW, k=3,4,.... In the quantity Wk, interactions between k-tuples of atoms play role, based on the concept of Steiner distance. It is shown that the term W+λWk provides an approximation for the boiling points of alkanes better than W itself. The best such approximation is obtained for k=7.
