摘要
Like many other properties of the molecular orbital (MO), such as energy level,electron negativity and charge distribution, the binding force of the molecular orbitalis regarded as an important physical concept to describe the binding property of themolecular orbital. The MO’s are divided into binding orbital, nonbinding orbital andantibinding orbital according to their respective binding effect. The binding charac-ter of an MO can be determined through the measurement of the changes in
