zjxitcc 发表于 2023-4-26 17:07 我明白了,非常感谢您,我还有一个问题想请教您,下面是我算的另外一个分子的垂直激发能,这个分子它的第一激发态的振子强度是0,是跃迁禁阻的。对于这个分子来说,它的Optical gap是S0-S2的垂直激发能3.6787 eV吗? Excited state symmetry could not be determined. Excited State 1: Singlet-?Sym 3.0349 eV 408.52 nm f=0.0000 <S**2>=0.000 149 ->150 0.70577 This state for optimization and/or second-order correction. Total Energy, E(TD-HF/TD-DFT) = -1817.97132222 Copying the excited state density for this state as the 1-particle RhoCI density. Excited state symmetry could not be determined. Excited State 2: Singlet-?Sym 3.6787 eV 337.03 nm f=1.0353 <S**2>=0.000 147 ->152 -0.18342 149 ->152 0.64022 149 ->159 0.17594 |
