站在计算化学入门的门槛上

It comes with the Jaguar program, it's just the old Hay-Wadt ECP+basis. In Gaussian, you get the same basis set by specifying a GEN basis with LANL2DZ on Pt, 6-31G* on everything else, AND also read in the LANL2DZ pseudo-potentials using PSEUDO=READ.

In Gaussian, you also have the option of adding some f-type polarization fro Pt without loosing too much performance, and also to split the basis a bit.

What is the LACVP basis set?
The LACVP series of basis sets is a combination of the successful 6-31G basis set with the LANL2DZ effective core basis set. Specifically the atoms H - Ar are described with the 6-31G (or 6-31G*, 6-31+G** etc) basis set while heavier atoms are modeled using the LANL2DZ basis set.

The atoms available in LACVP are shown in the following periodic table
