Poe 发表于 2019-1-18 15:24 Please try to use the functionals such as M06-2X or wB97XD. Sometimes, B3LYP is not fitted to TD-DFT. |
catenarygong 发表于 2019-1-18 13:10 十分感谢你的回复。LUMO轨道是pi*轨道,HOMO轨道是sigma轨道,这个过程是一个宇称禁阻的过程,所以振子强度几乎为零,而且不发射荧光,这么理解可以吗? |

Sorry my computer cannot input Chinese As your figure displayed, the LUMO orbitals is mostly like the conjugated-pi orbitals of the right segment. But the HOMO orbitals is mostly like the sigma orbitals, which is mostly vertical to the pi orbitals. |
