Graph Theoretical Analysis of Zigzag Polyhexamethylene Biguanide, Polyhexamethylene Adipamide, Polyhexamethylene Biguanide Gauze and Polyhexamethylene Biguanide Hydrochloride (PHMB) Boron Nitride Nanotubes (BNNTs), Amorphous Boron Nitride Nanotubes (a-BNNTs) and Hexagonal Boron Nitride Nanotubes (h-BNNTs)

[摘要] In this editorial, the relationship among energy, electric quadrupoleand hexadecapole moments with a topological index has knownPadmakar-Ivan (PI) index of some dLوٴerent types of zigzagpolyhexamethylene biguanide, polyhexamethylene adipamide,polyhexamethylene biguanide gauze and polyhexamethylenebiguanide hydrochloride (phmb) Boron Nitride Nanotubes (BNNTs),Amorphous Boron Nitride Nanotubes (a-BNNTs) and HexagonalBoron Nitride Nanotubes (h-BNNTs) is presented. Based on the graphtheory, a new method for the prediction of topological, quantumchemical, physical and molecular spectroscopic properties and alsoother properties of zigzag polyhexamethylene biguanide,polyhexamethylene adipamide, polyhexamethylene biguanide gauzeand polyhexamethylene biguanide hydrochloride (phmb) BoronNitride Nanotubes (BNNTs), Amorphous Boron Nitride Nanotubes (aBNNTs) and Hexagonal Boron Nitride Nanotubes (h-BNNTs) isinvestigated [1-10]. Furthermore, graph theory has been extensivelyapplied to predict the topological, quantum chemical, physical andmolecular spectroscopic properties of small molecules such as BoronNitride Nanotubes (BNNTs), Amorphous Boron Nitride Nanotubes (aBNNTs) and Hexagonal Boron Nitride Nanotubes (h-BNNTs) throughQuantitative Structure-Activity Relationship (QSAR) and QuantitativeStructure-Property Relationship (QSPR) studies [11-22]. Also, thisdemonstrates strong correlations among quantum chemical, physicaland molecular spectroscopic properties and one more topologicalindices. It should be noted that topological indices present amathematical definLtLon arising from the field of graph theory.
