“Inductive” electronegativity scale

Computational and Theoretical Chemistry, 1999
A new approach to the calculation of group electronegativity is introduced on the basis of previously elaborated additive models for steric and inductive effects. The newly derived 'inductive' group- electronegativities χ1 correlate well with other well-established electronegativity X scales.

Ab initio calculations, electronegativity equalisation and group electronegativity

Proceedings of the Indian Academy of Sciences - Section A, 1988
A correspondence betweenab initio calculations, the principle of electronegativity equalisation and group electronegativity has been established within the framework of Mulliken population analysis. Using this we have calculated electronegativities of some 37 groups/atoms.

Electronegativity—a perspective

Journal of Molecular Modeling, 2018
Electronegativity is a very useful concept but it is not a physical observable; it cannot be determined experimentally. Most practicing chemists view it as the electron-attracting power of an atom in a molecule. Various formulations of electronegativity have been proposed on this basis, and predictions made using different formulations generally agree ...

Electronegativity and redox reactions

Physical Chemistry Chemical Physics, 2016
Using the maximum hardness principle, we show that the oxidation potential of a molecule increases as its electronegativity increases and also increases as its electronegativity in its oxidized state increases.

Electronegativity in Quantum Chemistry

Russian Journal of Organic Chemistry, 2002
The possibility is discussed for determination of chemical potential (electronegativity) of an electron-nucleus system in terms of the quantum-mechanical density functional theory (DFT). The principle of complete leveling of chemical potentials of natural orbitals, formulated in the framework of DFT, cannot be regarded now as justified. The calculation
