[求助] 分子的单线态和三线态激发态能量模拟计算 已有1人参与

如题。请高手指教如何进行命令的编写来计算有机小分子的单线态(S1)和三线态(T1)激发态能量。本人做发光材料的。现在用的是高斯软件通过SSH Secure Shell Client上传到单位服务器进行计算。
看一些文献有如下的说明,
Quantum chemical calculations. All calculations were performed using the
Gaussian 09 program package. The geometries in the ground state were optimized
via DFT calculations at the B3LYP/6-31G* level. Vertical absorption energies (EVA)
were calculated based on TD-DFT with the B3LYP, PBE0, MPW1B95, BMK, M06-
2X and M06-HF functionals using 6-31G* basis sets. The calculated EVA(S1)
corresponding to LE or CT transitions were distinguished by orbital transition
analyses. Based on the relationship between q and the optimal HF% (OHF), that is,
OHF ¼ 42q, EVA(1CT, OHF) was read from the fitted straight line of the EVA(1CT)–
HF% points plotted on a log–log scale (Supplementary Fig. 2), and E0–0(1CT) was
obtained using a common gap of 0.24 eV between E0–0(1CT) and EVA(1CT, OHF).
Furthermore, by looking at the change in EVA(S1)–EVA(T1) with HF%, we
distinguished the EVA(T1) points corresponding to the 3CT or 3LE transitions and
calculate E0–0(3CT) and E0–0(3LE) from them, respectively (Supplementary Fig. 2
and Table 1). For more details on the calculations of CT amount (q), optimal HF%,
E0–0(1CT), E0–0(3CT) and E0–0(3LE), see our previous report30.
水平低,看不懂。
请高手解答!

通过这个文字,我知道,你是做延时荧光的TADF,看的文章是日本实验组adachi教授的文章,你这个文章,我没记错的话,应该是张其胜大牛的jacs。最新的。不知道这些对不对
高斯优化激发态的方法,可见我的这个帖子:

对应,选用的泛函的方式,她是借助multiwfn计算的。在我的这个帖子,我有问过。

It doesn't matter how slow you are, as long as you're determined to get there, you'll get there.

你好,我对这个理论模拟刚入门。比如,我现在用#p opt b3lyp/6-31g geom=connectivity pop=reg,就算算分子轨道分布,HOMO和LUMO能级值。现在想计算有机小分子的S1和T1能量。这个基组该怎么选,现在单位用的是G03版本的。#p opt td b3lyp/6-311g++G(d) geom=connectivity pop=reg,这样写对吗?能否帮忙写个运行的基组命令呢?

多看看这个,你是优化s1还是优化t1
