谢谢指点。
1.将内存调整为1024MB(%mem=1024MB),目前能够正常计算。
2.关于基组的选择,一方面我参考了组内同学的工作,他们在结构优化和振动分析时选择的是相同的混合基组,在计算单点能时选择了更贵的方法计算(M06,SDD 6-311++G(d,p))我也依葫芦画瓢,先照着样子做一遍。
3.我也想安装Linux系统,可是一时半会儿还没弄懂怎么安装,刚在B站上找了一个教程,还在琢磨怎么安装,不知道老师是否有更加详细的教程。
4.下面是我们组同学的计算方法,麻烦您给看一下是否合理?
The B3LYP density functional method was employed to carry out all the
geometry optimizations. For the geometry optimizations, the LANL2DZ basis set
with the LANL2DZ pseudopotential was utilized for La and I atoms. The 6-31G(d)
basis set was used for other atoms. Vibrational frequency analyses at the same level of
the theory were performed on all the optimized geometries to characterize them as
local minima (no imaginary frequency) or transition states (one imaginary frequency).
In addition, intrinsic reaction coordinate (IRC) calculations were used to verify that
the transition state connect with appropriate reactant and product. The M06
functional was employed to run single-point energy calculations based on the
optimized structures with larger basis sets (SDD for La, I atoms and 6-311++G(d,p)
for other atoms). The Gibbs energy was determined by adding the single-point energy
calculated at larger basis sets and the gas-phase thermal correction to the Gibbs
energy obtained from the vibrational frequency analysis. All calculations were carried
out with the Gaussian 09 (Revision C.01) suite of programs.
再次感谢。 |
