摘　　要：使用群论方法研究了NH_3分子的正则振动模式,构造了NH_3分子总的特征标,确定NH_3分子的正则振动模式的不可约表示为A_1和E.使用投影算符构造出NH_3分子的6个正则振动模式,给出图示,它们都具有拉曼活性和红外活性.In this paper the normal vibrations of NH3 molecule has been studied by using the group theory. Firstly, the group character of NH3 molecule has been obtained and the irreducible representations of the normal vibrations of NH3 molecule are A1 and E. Six normal vibrations of NH3 molecule have been gotten by using the projection operators and they all have infrared activity and Raman activity. The graphic expression of six normal vibrations has been given.
