分子的單線態(tài)和三線態(tài)激發(fā)態(tài)能量模擬計算 已有1人參與

如題。請高手指教如何進(jìn)行命令的編寫來計算有機小分子的單線態(tài)(S1)和三線態(tài)(T1)激發(fā)態(tài)能量。本人做發(fā)光材料的。現(xiàn)在用的是高斯軟件通過SSH Secure Shell Client上傳到單位服務(wù)器進(jìn)行計算。 看一些文獻(xiàn)有如下的說明, 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。 請高手解答! |

通過這個文字,我知道,你是做延時熒光的TADF,看的文章是日本實驗組adachi教授的文章,你這個文章,我沒記錯的話,應(yīng)該是張其勝大牛的jacs。最新的。不知道這些對不對 高斯優(yōu)化激發(fā)態(tài)的方法,可見我的這個帖子: http://www.gaoyang168.com/bbs/viewthread.php?tid=7860007 對應(yīng),選用的泛函的方式,她是借助multiwfn計算的。在我的這個帖子,我有問過。 http://ccc.keinsci.com/forum.php?mod=viewthread&tid=415 |
