摘　　要：评述了Lewis酸碱电子理论及氟离子亲合能的概念,指出了可以通过离子回旋共振实验方法和量子化学理论方法获得氟离子亲合能数值以定量确定Lewis酸性强度,并介绍了表示Lewis酸性强度的PF^-标度。This paper reviewed the concepts of Lewis acid-base theory and fluoride ion affinity. The fluoride ion affinity, which is used to quantitatively measure the Lewis acidity strength, can be attained by ionic cyclotron resonance spectroscopy and quantum chemical approach. The PF- scale for the representation of acidity strength was also introduced.

关 键 词：LEWIS酸 酸性强度 氟离子亲合能
