The molecular connectivity 4XPC index was examined for its ability to describe uniquely
molecules containing substituted benzene rings. The subgraphs comprising this index were …

Molecular connectivities (x values) are topological indices devised by RandiE (1975), and
extensively developed by Kier and Hall (1976). They have been shown tocorrelatewith a …

An investigation was made into the use of linearand quadratic discriminant analysis, along
with K nearest-neighbor analysis, in the classification of a set of 51 compounds which were …

The shape or steric configuration of a molecule is known to have an influence on physical
properties and biological activity. The quantitation of this structural aspect, however, is quite …

Molecular connectivity, the manner in which atoms are connected or branched in a
molecule, is a fundamental characteristic of the structure. It is well known that chain isomers …

The extension of the molecular connectivity concept to the treatment of heteroatom
molecules affords an opportunity to examine structure‐activity relationships in a wide variety …

The molecular connectivity index is shown to be linearly related to the octanol—water
partition coefficients of a variety of monofunctional chemical classes including esters …

The molecular connectivity 3χp index has been evaluated for its structure information
content. This index has been found to relate closely to a quantitation of the number of …

The molecular connectivity index, X, initially designed for hydrocarbons, has been formally
extended to molecules containing heteroatoms. The δ value of the heteroatom is modified to …

The possible relationship between molecular connectivity indexes, mx, and E8, a
thermodynamically derived parameter used to estimate steric effects in organic reactions …
