In the case of "No map to state **, you need to resolve more vectors" messages, this is usually an indication that one did not include enough excited states in the TD or CIS calculation. The "States=N" option to the "TD" or "CIS" keywords tells how many excited states to include in an excited state energy calculation. If this is not specified, the default value will be "States=3". The recommended value is to include a minimum of 2 or 3 more states than the state of interest. Thus, if you want to perform a geometry optimization for excited state 5, for example, I would recommend at least using "States=7" or "States=8". The geometry optimization will be done for one excited state M, selected with "Root=M", and one has to make sure that enough states are included in the CIS or TD expansion by having "States=N" where N is larger than M. 建議你多看看論壇中關于此類錯誤的解答!祝你好運! |

為什么不可以呢?如果你的初始猜測和激發(fā)態(tài)的幾何構型一模一樣,這樣優(yōu)化激發(fā)態(tài)難道就錯了嗎?而且當你感興趣的激發(fā)態(tài)和基態(tài)構型變化很大時,你再用基態(tài)幾何構型優(yōu)化,很可能是優(yōu)化不出來的。舉個簡單的例子,如乙烯分子,基態(tài)具有D2h點群的對稱性,如果你想優(yōu)化激發(fā)態(tài)(pi-pi*)的幾何構型,還保持基態(tài)D2h點群對稱性,估計你很可能是優(yōu)化不出來的。 |
