متن کاملTopological relationship between electric quadrupole, hexadecapole moments, energy and Padmakar–Ivan index in armchair polyhex nanotubes TUVC6[2p,q]
The electric quadrupole, hexadecapole moments, energy (kJmol -1) for some armchair polyhex carbon nanotubes TUVC6[2p,q] are performed by Beck-Lee-Yang-Parr [B3LYP] on 3-21G basis set using the standard procedure indices GAUSSIAN 98, then the Padmakar-Ivan (PI) index of TUVC6[2p,q] nanotubes in the terms of their circumference (2p) and lengh (q) is calculated and the relationships between the Pa...

متن کاملSome Graphs with Extremal Pi Index
The Padmakar-Ivan (PI) index is a Wiener-Szeged-like topological index, which reflects certain structural features of organic molecules. In this paper, we study the maximum PI indices and the minimum PI indices for trees and unicyclic graphs respectively.

most extensively analysed fungal sequences. As there are now barcode sequences covering all kingdoms of multicellular life, and taxonomists in museums are working hard to keep the molecular information connected to the traditional repositories and species definitions, barcodes offer the opportunity to expand species identification to situations where skilled taxonomists may not be at hand. “As ...
متن کاملComputing Vertex PI Index of Tetrathiafulvalene Dendrimers
General formulas are obtained for the vertex Padmakar-Ivan index (PIv) of tetrathiafulvalene (TTF) dendrimer, whereby TTF units we are employed as branching centers. The PIv index is a Wiener-Szeged-like index developed very recently. This topological index is defined as the summation of all sums of nu(e) and nv(e), over all edges of connected graph G.
