【求助】频率较正因子的问题。
|
|||
|
向虫友求助关于频率较正的问题。输入文件： %Chk=ethylene.chk # b3lyp/6-31G* Opt freq=(readisotopes,raman) Pop=full ethylene 0 1 C 0 0.660202 -0.011475 0.030182 C 0 -0.660172 0.011520 -0.030106 H 0 1.263031 0.752045 -0.424927 H 0 1.192139 -0.794861 0.536957 H 0 -1.263031 -0.752045 0.424927 H 0 -1.192169 0.794785 -0.537079 298.15 1.0 0.9804 12 1 12 2 1 3 1 4 1 5 1 6 发现根本就没有起作用。这是什么原因呢？google和搜索了下也没有找到答案。 此为问题一。 于是，我又采用如下输入文件(Gaussian 03)，却老是报错，研究了半天没找出原因。这又是什么引起的？ 此为问题二。 %Chk=ethylene.chk # b3lyp/6-31G* opt freq=raman scale=0.9804 temperature=298.15 pressure=1.0 ethylene 0 1 C 0 0.660202 -0.011475 0.030182 C 0 -0.660172 0.011520 -0.030106 H 0 1.263031 0.752045 -0.424927 H 0 1.192139 -0.794861 0.536957 H 0 -1.263031 -0.752045 0.424927 H 0 -1.192169 0.794785 -0.537079 谢谢！解决问题，一个问题2个金币。意思一下。 [ Last edited by gonemrc on 2009-11-22 at 17:09 ] |

1、你所谓的加了校正因子不起作用，是不对的。你没有认真看输出文件，也没有好好理解高斯手册。别在那个高斯程序的窗口中看，那个显示不全，要用文本编辑软件查看log文件（windows下默认是out文件），另外任何时候都要在#后面加个p，这样会输出很多有用的信息，再次，高斯03手册中文版207页：“注意如果定义了换算因子，只会反映在热化学数据中，频率不做换算。”、英文版216给出：“Note that if scaling is specified, only the thermochemistry data reflects it: the frequencies themselves are not scaled.”，所以你只是看到频率没发生变化，但由此引起的零点校正项（包括能量、焓、吉布斯能）都不一样了，你没有看到。 2、也许是你的g03版本有问题，你的是b01，我用e01跑，没发现问题。虽然temperature=298.15 pressure=1.0本来就是默认值，没有必要写。还有开始第一个例子中，结尾处给的那些个是什么？如果是链接关系表，前面应该有geom=connect，如果是，根本没必要，如果不是，你需要一个解释。 [ Last edited by zhangmt on 2009-11-23 at 00:44 ] |

谢谢楼上虫友的精彩回复。是这样的。 对于问题一，我参看了网上的一些说法， 有人提到，在out文件中，如果出现下面的消息： ------------------- - Thermochemistry - ------------------- Temperature 298.150 Kelvin. Pressure 2.00000 Atm. Thermochemistry will use frequencies scaled by 0.9900. 表示较正已经生效，而实际上我的第一个例子中， ------------------- - Thermochemistry - ------------------- Temperature 298.150 Kelvin. Pressure 1.00000 Atm. Atom 1 has atomic number 6 and mass 12.00000 Atom 2 has atomic number 6 and mass 12.00000 Atom 3 has atomic number 1 and mass 1.00783 Atom 4 has atomic number 1 and mass 1.00783 Atom 5 has atomic number 1 and mass 1.00783 Atom 6 has atomic number 1 and mass 1.00783 根本没有提及我的较正因子已经起效的问题。至于后面的 12 1 12 1 …… …… 这些只是我根据Freq=ReadIso的关键字指定了一下同位素， 因为我发现用了这个关键字，虽然前面已经写了温度，压力 等数据，如果不写的话也跑不起来。 对于问题二，我就非常纳闷了，同是03版，而且手册上也指定了这个 关键字，怎么会因为小修版本的差别而出错呢？ 谢谢！ |
