Note on the Hyper-Wiener Index [PDF]
Journal of the Serbian Chemical Society, 2003 The hyper-Wiener index WW of a chemical tree T is defined as the sum of the products n1n2, over all pairs u, u of vertices of T, where n1 and n2 are the number of vertices of T, lying on the two sides of the path which connects u and u.

International Journal of Quantum Chemistry, 1982 AbstractA method is developed for obtaining the spectra of trees of NMR and chemical interests. The characteristic polynomials of branched trees can be obtained in terms of the characteristic polynomials of unbranched trees and branches by pruning the tree at the joints.

On the Sombor index of chemical trees
Mathematica Montisnigri, 2021 We give sharp bounds on the Sombor index of chemical trees and characterize the cases of the equalities. We stated conjectures regarding second maximal chemical trees of order n with respect to Sombor index, when n ≡ 0(mod 3) and n ≡ 1(mod 3).
