摘要: 本文用群论方法推出多原子分子正则振动模式的可约表示特征标公式,在IBM微机上实现程序化,使红外光谱振动模式分解更加简便、实用。并且给出ABn(n=2~12)构型分子和碳原子簇C_n(n=20,24,50,60,70,84)的振动模式不可约表示。

Abstract: The character of reducible representation for normal models of multi-atomic molecular system is formulated by group theoretical approach.The formula is programmed in IBMpersonal computer, which makes the reduction of normal models in infared spectrum simple and practical, The ine-ducible representation of normal models for some ABn(n = 2~12) molecules and carbon clusters Ca(w =-20, 24, 50, 60, 70, 84) are also presented.

Key words: Infrared spectrum, Reduction of vibration models, Carbon clusters
