Electronegativity and inductive and mesomeric parameters of atomic groups: A semiempirical quantum chemical estimation

The electronegativity, the inductive parameter, and the mesomeric dipole moments of substituents depend on the electronic structure characteristics of organic molecules calculated by the CNDO/2, INDO, MINDO, MINDO/3, MNDO, and AMI methods. It is shown that the electronegativity as well as the inductive and mesomeric characteristics of atomic groups may be estimated by semiempirical quantum chemical methods.
