感谢Sob老师的回复,之前只是怀疑g09和g16对激发态进行优化所使用的方法不一样,可能数据提供的不确切,下面的是我用相同的结构相同结构做的分子的S1态的计算(调用路径、关键词、激发能):
Gaussian16
Initial command:
/opt/soft/gauss/g16/g16/l1.exe "/tmp/ram01f/gauss16.507612.mu01/Gau-18729.inp" -scrdir="/tmp/ram01f/gauss16.507612.mu01/"
Entering Link 1 = /opt/soft/gauss/g16/g16/l1.exe PID= 18730.
%NProcShared=12
Will use up to 12 processors via shared memory.
%mem=500MW
%chk=bmbpy-nidoB-B3lyp-TD-S-opt-freqNM.chk
------------------------------------------------------------------
#p td=(singlets,root=1,nstate=5) opt Frequency=SaveNM b3lyp/genecp
Excitation energies and oscillator strengths:
Excited State 1: Singlet-A 1.0877 eV 1139.87 nm f=0.0062 <S**2>=0.000
189 ->190 0.70692
This state for optimization and/or second-order correction.
Total Energy, E(TD-HF/TD-DFT) = -2685.44800812
Copying the excited state density for this state as the 1-particle RhoCI density.
Excited State 2: Singlet-A 2.0383 eV 608.26 nm f=0.0661 <S**2>=0.000
188 ->190 0.70350
Gaussian09
Initial command:
/opt/soft/gauss/g09d01/g09/l1.exe "/tmp/ram01f/gauss09d01.446329.mu01/Gau-3624.inp" -scrdir="/tmp/ram01f/gauss09d01.446329.mu01/"
Entering Link 1 = /opt/soft/gauss/g09d01/g09/l1.exe PID= 3637.
%NProcShared=12
Will use up to 12 processors via shared memory.
%mem=500MW
%chk=bmbpy-nidoB-B3lyp-TD-S-opt.chk
-------------------------------------------------
#p td(singlets,root=1,nstate=15) opt b3lyp/genecp
Excitation energies and oscillator strengths:
Excited State 1: Singlet-A 2.2311 eV 555.71 nm f=0.0420 <S**2>=0.000
188 ->190 0.23078
189 ->190 0.66650
This state for optimization and/or second-order correction.
Total Energy, E(TD-HF/TD-KS) = -2685.42886721
Copying the excited state density for this state as the 1-particle RhoCI density.
Excited State 2: Singlet-A 2.4794 eV 500.07 nm f=0.0220 <S**2>=0.000
188 ->190 0.66537
189 ->190 -0.23358
激发能差的特别多,不知道是不是Gaussian不同版本之间采用的优化方法导致的
