l9999错误是优化圈数不够,把out文件保存成gjf,修改后接着优化。

这样比较省事。

或者在原来输入文件opt中加入maxcyc=500,把优化圈数加大到500

L1002错误贋势基组不对,换基组,或者用guess=Indo

L9999

Optimizationstopped.

  --WrongnumberofNegativeeigenvalues:

Desired=  1Actual=  3

  --Flagresettopreventarchiving.

这是你原来贴的出错信息。

显然,gaussian检测了虚频个数,发现是3个而非1个——过渡态有且只有一个虚频,从而终止,显示出错。

加上noeigentest的意思是在优化过程中不必每步都去检测虚频个数,而是按照最可能的方式继续寻找下去,到跑完为止,所以如果你对过渡态的初始构型不是非常有把握的情况下,加上noeigen是比较不错的选择。

但你现在继续出状况,却没有贴新的出错信息,我没法猜这次是什么问题。

同时你那个命令行#b3lyp/6-31++g(d,p)opt=(ts,calcfc,noeigen)freqtest  

改成#pb3lyp/6-31++g(d,p)opt=(ts,calcfc,noeigen)freq

也就是任何时候#后面都要加一个p,结尾那个test不要写,被人笑话的。

InaccuratequadratureinCalDSu错误解决方法

 

g09/g03输出文件最后几行大致如下:

552009.

Jobcputime:

0days0hours0minutes3.1seconds.

Filelengths(MBytes):

RWF=13Int=0D2E=0Chk=13Scr=1

 

解决方法

1.对某些分子,可以设置guess=indo。

(Guess=indo的意思是:

使用Gaussian98的默认初始猜测:

对第一行元素是INDO,第二行元素是CNDO,第三行及以后的元素是Huckel。

如果不写Guess=indo,则使用Gaussian03的默认初始猜测:

全部使用Huckel初始猜测。

Guess=indo的用处:

使比较差的初始构型,能比较顺利地通过初始猜测。

2.对于对称分子,设置scf(dsymm)强制使用密度对称。

3.对于对称分子,设置全局nosymm,降低对称性。

4.使用scf(novaracc)也可能会产生或消除这个错误。

5.加上int(untrafine),不过这个改变了积分网格,这个计算出的能量不能与同类计算直接比较。

6.最佳解决方法:

加关键词int(NoXCTest)网格问题(G09默认的精度检测方法不适用,加上Int=NoXCTest),SkiptestsofnumericalaccuracyofXCquadrature(g09手册)。

需要检测结果波函数是否正确。

可同时加guess=indo。

Errorininternalcoordinatesystem.

可在opt中加入cartesian

例如:

%chk=TS3-D-itm3-eoc-4.chk

%mem=45000MB

%NProcShared=8

#B3LYP/6-31G**iop(5/13=1)iop(2/11=1)

#scf=(maxcycle=200)

#opt=(cartesian,TS,calcfc,noeigen,maxcycle=200)freq

#geom=allcheck
