咨询的问题如下(2个问题): 1.步骤3(激发能计算)的计算结果输出如下:
Excited State 1: 2.041-A 1.2682 eV 977.63 nm f=0.0001 <S**2>=0.791
41B -> 62B 0.10820
53B -> 62B 0.35379
55B -> 62B -0.12295
58B -> 62B 0.73445
59B -> 62B -0.48080
This state for optimization and/or second-order correction.
Total Energy, E(TD-HF/TD-DFT) = -870.302903856
Copying the excited state density for this state as the 1-particle RhoCI density.

为什么S**2不是0.75? 这里0.892、2.717可以当做自由基吗?用不用考虑自旋污染呢?能否基于此计算结果进行后续的计算(垂直发射能计算)? 2.步骤5的计算输出结果如下:
Excited State 1: 2.040-A 1.2888 eV 962.01 nm f=0.0000 <S**2>=0.791
41B -> 62B 0.10808

59B -> 62B 0.47432
