[交流] 【求助】这两个基组的区别 已有4人参与

请问6-311G* Wachters-Hay basis set和6-311G* Pople basis set这两个基组是一回事吗,如果不是,提交任务时如何区分,谢谢

这应该不是高斯自带的标准基组,需要编程植入。

除了查阅相应的文献外,恐怕没有更好的方法得知它们的区别。
愿好运与快乐伴随你!

我觉得在高斯中会自动调用的,楼主不妨咨询一下高斯公司
6-311G: Specifies the 6-311G basis for first-row atoms and the McLean-Chandler (12s,9p) → (621111,52111) basis sets for second-row atoms [McLean80, Raghavachari80b] (note that the basis sets for P, S, and Cl are those called negative ion basis sets by McLean and Chandler; these were deemed to give better results for neutral molecules as well), the basis set of Blaudeau and coworkers for Ca and K [Blaudeau97], the Wachters-Hay [Wachters70, Hay77] all electron basis set for the first transition row, using the scaling factors of Raghavachari and Trucks [Raghavachari89], and the 6-311G basis set of McGrath, Curtiss and coworkers for the other elements in the third row [Binning90, McGrath91, Curtiss95]. Note that Raghavachari and Trucks recommend both scaling and including diffuse functions when using the Wachters-Hay basis set for first transition row elements; the 6-311+G form must be specified to include the diffuse functions. MC-311G is a synonym for 6-311G.
前途光明,出路难觅!

谢谢大家的关心。
我也看过楼上贴的内容,我也感觉高斯中会自动调用。6-311G* Wachters-Hay basis set对第一行的过渡金属自动调用,6-311G* Pople basis set对C,H,O等元素自动调用。希望高手能够证实或证伪,期待中,谢谢!
