[求助] 求助关于TD-DFT计算的Excitation energies and oscillator strengths问题

大家有没有遇到这样的问题：
小弟刚接触高斯计算不久，有很多疑问，请大家谅解。
在做TD-DFT计算的时候，我们可以得到关于Excitation energies and oscillator strengths 的很多数据，该怎样选取呢？
1.oscillator strengths 是什么意思啊？这个值越大的话说明这个配合物越稳定吗？
2.实验测得的紫外吸收峰在305nm。其中有一组数据是关于波长的，但是计算值在305nm左右的数值处的f值很小，是不是不能用这组数据，而应该选取f值大的Excited State 8和10 的数值处得波长呢？这是不是说明计算值与实验值不太吻合呢？
请大家帮帮忙，谢谢了.
