WebA novel topological index for the characterization of chemical graphs, derived from the reciprocal distance matrix and named the Harary index in honor of Professor Frank Harary, has been introduced. The Harary index is not a unique molecular descriptor; the smallest pair of the alkane trees with identical Harary indices has been detected in the octane family. WebMar 30, 2024 · The Wiener index and the Harary index have many application in chemistry and there are lots of papers dealing with these two indices, see [7, 10, 13, 16].. An Eulerian cycle is a closed walk in a graph that visits every edge exactly once. A graph containing an Eulerian cycle is called an Eulerian graph.According to the classical result by Euler [], a …
The generalized reciprocal distance matrix of graphs
WebSep 1, 2015 · The Harary matrix RD(G) of G, which is also known as the reciprocal distance matrix was introduced by Ivanciuc et al. [10] as an important molecular matrix to research this interaction. We consider simple (molecular) graphs, that is, graphs without multiple edges and loops. Undefined notation and terminology can be found in [2]. WebAnother generalization of the Balaban index J, so as to account for heteroatoms in the molecule, is the - Barysz index calculated on the - Barysz distance matrix. [Pg.23] JJ indices derived from the - Wiener matrix were proposed as a generalization of the Balaban index in analogy with the Kier-Hall -> connectivity indices. how many inches is 5.3 centimeters
