【求助】G09熒光光譜例子 運(yùn)行出錯(cuò)
|
|||||
|
用gaussian09計(jì)算乙醛分子在乙醇溶液中的熒光光譜。根據(jù)手冊,一共分成7個(gè)步驟,http://www.gaussian.com/g_tech/g_ur/k_scrf.htm 但是計(jì)算到第六步出了問題。 輸入文件如下: %chk=06-ac # B3LYP/6-31+G(d,p) TD=(Read,NStates=6,Root=1) SCRF=(Solvent=Ethanol,StateSpecific,Read) Geom=Check Guess=Read Acetaldehyde emission state-specific solvation at first excited state optimized geometry 0 1 NonEq=write 出錯(cuò)信息: PCMU: Requested matrix not present on file. Error termination via Lnk1e in /public/g09/l601.exe 請教大家,如何解決這個(gè)問題呢? 謝謝! |

請將StateSpecific關(guān)鍵詞改為ExternalIteration,這個(gè)是Gaussian 09的一個(gè)BUG,我專門寫信問過Gaussian公司,這個(gè)BUG在B01中已經(jīng)修正,但是在A01和A02中都存在,所以你需要把這個(gè)例子中所有的StateSpecific改為ExternalIteration,這兩個(gè)關(guān)鍵詞作用是一樣的,在B01中使用這兩個(gè)關(guān)鍵詞的結(jié)果是一致的,但是在A01中和A02中使用StateSpecific,即便能得到結(jié)果,比如這個(gè)例子中計(jì)算吸收光譜那一步,其結(jié)果也是錯(cuò)的,它僅僅算了真正的StateSpecific中的第一步而已。 Gaussian公司的回復(fù)郵件: Thank you for your inquiry. The problem with the example shown in the manual is related to the "StateSpecific" option. Unfortunately, the "StateSpecific" option was connected incorrectly in the current version of G09, but this will be fixed in the next minor revision. As a workaround, you can use the "ExternalIteration" option instead of the "StateSpecific" option (for both the state specific vertical excitation and the emission state specific solvation). The "ExternalIteration" option is a generalization of the "StateSpecific" option. So, please, try the example in the manual again with the only change of removing "StateSpecific" and adding "ExternalIteration" instead. For example, %nproc=16 %mem=2000mb %chk=06-ac # B3LYP/6-31+G(d,p) TD=(Read,NStates=6,Root=1) SCRF=(Solvent=Ethanol,ExternalIteration,Read) Geom=Check Guess=Read Acetaldehyde emission state-specific solvation at first excited state optimized geometry 0 1 NonEq=write |
