输出文件的末尾显示如下
No map to state 1
You need to solve for more vectors in order to follow this state.

我看了之前其他人遇到的问题,公社论坛上回复加大Nstates试试,不过我还是有几个问题不明白,想请教一下各位前辈们:
1.我研究的是root=1,按理说Nstates=20已经是可以了,难道还需要加大Nstates?
2.我看了输出文件中最后部分荧光发射波长的计算,荧光发射波长竟为5310.95 nm,这是否可以知道homo与lumo之间能级间隔很小?
Excitation energies and oscillator strengths:
Excited State 1: Singlet-A 0.2335 eV 5310.95 nm f=0.0007 <S**2>=0.000
141 ->142 0.70686
This state for optimization and/or second-order correction.
Copying the excited state density for this state as the 1-particle RhoCI density.
Excited State 2: Singlet-A 2.5742 eV 481.65 nm f=0.0000 <S**2>=0.000
141 ->143 -0.69927
Excited State 3: Singlet-A 2.7243 eV 455.11 nm f=0.0002 <S**2>=0.000
137 ->142 -0.18126
138 ->142 -0.56218
139 ->142 0.37374
3.在输出文件的前半部分,出现的是第一激发态的能量比第二激发态能量高,这是因为出现了能级交错吗?
Excitation energies and oscillator strengths:
Excited State 1: Singlet-A 2.8343 eV 437.44 nm f=0.0009 <S**2>=0.000
138 ->142 -0.47790
139 ->142 0.34560
140 ->142 0.36395
This state for optimization and/or second-order correction.
Copying the excited state density for this state as the 1-particle RhoCI density.
Excited State 2: Singlet-A 2.7638 eV 448.60 nm f=0.0000 <S**2>=0.000
141 ->142 -0.70215
Excited State 3: Singlet-A 3.0116 eV 411.69 nm f=0.0001 <S**2>=0.000
138 ->142 0.35680
139 ->142 0.59437
4.出现 这样情况的体系是否不能单靠增大NStates来解决?是否有一些其他的推荐办法?
