老师,看一篇文章里面【Am and Eu were modeled with the small-core Stuttgart relativistic effective core potential with its associated basis set (with the most diffuse functions removed)】,这在高斯里面怎么写输入文件啊?
sob老师,我想问下审稿人给了一条意见“The cutoff distance for calculating VDW potentials is too large for these cases and obviously violate the minimum image convention, therefore the results is totally not convictive for the readers”.我设置的为18.5埃,审稿人说截断半径太大,我在文献里找到cutoff distance 值一共有4种,9.5,12.5,15.5,18.5埃,但文献都没给出解释,我不太理解的是“the minimum image convention”是什么意思,还有就是cutoff distance设置具体依据是什么,谢谢@Sobereva
谢谢老师,但我在MS帮助文件里看到这样一段话,“ in periodic crystalline systems, both van der Waals interactions and electrostatic interactions can be significant up to 15 Å, or more. For example, in a calculation of the energy as a function of cutoff distance in the hexapeptide crystal, [Ala-Pro-D-Phe]2, Kitson and Hagler showed that the non-bond energy accounted for changes from 63% to 97% of the asymptotic value as the cutoff distance was increased from 8 to 15 Å,而我计算的就是周期性晶体体系@Sobereva
