Characterization of molecular branching
WebAbstract. A topological index, based on the distance matrix of a molecule and derived by means of information theory, is proposed for characterization of skeletal branching. In all cases studied it has differentiated isomeric structures. WebThe chemical graph theory is a paramount section of mathematical chemistry. In this section, there are many topological parameters, that have very useful characteristics to study the molecular structure of chemicals. In this article, we investigate topological indices of concealed non-kekulean benzenoid hydrocarbon graph.
