Abstract:
In this paper, for the first time we have correlated the hardness (η), softness (s), and polarizability (P) with the electronegativity and the distortion (ΔR) of a single bond in a complex polyatomic system. The study also shows some interesting: trends as different types of bonds are distorted. We have suggested a new concept, "local bond hardness", in a complex polyatomic system. The molecules H2O, CH4, CH3Cl, and CH3F are chosen as primary test cases.
