[交流] 【讨论】一个关于基组设置的问题

Gaussian计算中的基组6-311G(d),它在Material Studio中Dmol计算是有与之对应的基组设置么?

比如:我选functional----GGA, Pw91
                 Core Treatment----Effective Core Potentials
                 Basis Set----DNP
不知道这样的设置与6-311G(d),有没有可比性呢?

好像是DNP是相当于6-31g**  你看看说明书吧

我也没有再查

The size of the DND basis is comparable to Gaussian 6-31G* basis sets, and DNP basis sets are comparable to 6-31G** sets. However, the numerical basis set is much more accurate than a Gaussian basis set of the same size.

Minimal basis sets are generally inadequate for anything but qualitative results, while DNP sets are the most reliable. The min, dn, dnd, and dnp options operate by instructing the program to ignore the extraneous functions. This is reflected in the output file when certain orbitals may be designated as eliminated from the basis set.



这是说明书里面的
