摘　　要：本文报导了[S_2MoS_2FeCl_2]^(2-)(简记为K_1)和[S_2MoS_2Fe(SPh)_2]^(2-)(简记为K_1′)两种簇阴离子的简正坐标分析的结果。振动基频的计算值与观测值符合良好,两者平均偏差都小于1.25%,证实了振动谱带的归属;确定了相应的力常数。最后讨论了所得结果的合理性和可靠性。The results of the normal coordinate analysis on two dianions [S_2MoS_2FeC1_2]^(2-) and [S_2MoS_2Fe(Sph)_2]^(2-) are reported. The calculated frequencies agree well with the observed ones and the mean deviations are all less than 1.25%. Thus the assignments of the main vibrational spectrum bands are confirmed and the corresponding force constants are obtained. Finally, the rationality and reliability of the results are discussed.
