The ideas of Mallion and Rouvray (1978), concerning the relevance of molecular topology to the prospects of obtaining, on the basis of the Aufbau Principle, a unique, n:-electronic ground-state configuration for an existent or hypothetical conjugated-system, are extended by considering a series of networks introduced by Balaban in 1978. It is shown by exploiting the properties of the eigenvalue...

It is well known that the chemical behavior of a compound is dependent upon the structure of itsmolecules. Quantitative structure – activity relationship (QSAR) studies and quantitative structure –property relationship (QSPR) studies are active areas of chemical research that focus on the nature ofthis dependency. Topological indices are the numerical value associated with chemical constitution...

Topological indices are the numerical value associated with chemical constitution purporting for correlation of chemical structure with various physical properties, chemical reactivity or biological activity. Graph theory is a delightful playground for the exploration of proof techniques in Discrete Mathematics and its results have applications in many areas of sciences. One of the useful indic...

All the drugs used as analgesic agent have some systemic side effects. For the researchers, the prospects of overcoming the side effects of a drug, achieving an effect at a much lower dose is very attractive. Modification of the structure of a known drug is one way to develop new drugs. For this purpose, we have optimized the pyrimidobenzimidazole derivatives using molecular modeling studies. Q...

As tropospheric chemical models become ever more complex, reliable ratecoefficient data for gas-phase hydrogen abstraction reactions involving tracehydrocarbons becomes increasingly necessary. There are hundreds of non-methane hydrocarbons (NMHCs) of potential importance to troposphericchemistry, many of which have not been subjected to experimental inquiry. Thisstudy—the fi...
