Abstract
The mean electronegativities which are satisfactory approximations for the equalized ones can be brought into close relation with the simplest molecular parameters. The force constants of diatomic molecules AlF, GaF, InF, TlF; SiF, GeF; NF, PF, PF+, AsF and SbF or of simple isolated bonds can be expressed by means of the equalized electronegativities, bond orders, bond strengths and interatomic distances. The performance of the Lennard-Jones parameters has been tested with the potential function proposed bySzőke in calculatingω e x e andα e , and found to be excellent. The role of the electronegativity in constructing the ential energy functions proves the validity of the assumption that there is a close connection between electronegativity and the energy relations of the molecules.
