The Meaning of Molecular Connectivity: A Bimolecular Accessibility Model

Sa？etak The simple molecular connectivity indices are analysed for the information in the bond terms. It is found that these terms reflect the relative accessibility of each bond to encounter other bonds of the same molecule in a milieu. The total possibility of each molecule to encounter another molecule in a bimolecular interaction is found to be the molecular connectivity index for that molecule. The molecular connectivity indices are interpreted to be the bimolecular interaction possibilities of a molecule in a milieu
