Gamess

En otros como el Gamess, las bases son análogas, pero se escriben de forma distinta:

$BASIS group (optional)
          GBASIS = MINI - Huzinaga's 3 gaussian minimal basis set.
                    Available H-Rn.

                    Available H-Kr, for NGAUSS=6, note that the
                    bases for K,Ca,Ga-Kr were changed 9/2006.
                 = N311 - Pople's "triple split" N-311G basis set.
                    Available H-Ne, for NGAUSS=6.
                    Selecting N311 implies MC for Na-Ar.
                 = DZV - "double zeta valence" basis set.
                    a synonym for DH for H,Li,Be-Ne,Al-Cl.
                    (14s,9p,3d)/[5s,3p,1d] for K-Ca.
                    (14s,11p,5d/[6s,4p,1d] for Ga-Kr.

                    (10s,6p)/[5s,3p] for Be-Ne.
                    a synonym for MC for Na-Ar.

                    (12s,9p)/[6s,5p] for Na-Ar.
                    Selecting MC implies 6-311G for H-Ne.
                 = CCn - Dunning-type Correlation Consistent basis
                    sets, officially called cc-pVnZ.
                    Use n = D,T,Q,5,6 to indicate the level of
                    polarization. These provide a hierachy of
                    basis sets suitable for recovering the
                    correlation energy.
                    Available for H-He, Li-Ne, Na-Ar, Ca, Ga-Kr
                 = ACCn - As CCn, but augmented with a set of diffuse
                    functions, e.g. aug-cc-pVnZ.
                 = CCnC - As CCn, but augmented with tight functions
                    for recovering core and core-valence
                    correlation, e.g. cc-pCVnZ.
                 = ACCnC- As CCn, but augmented with both tight and
                    diffuse functions, e.g. aug-cc-pCVnZ.
                 = PCn - Jensen Polarization Consistent basis sets.
                    n = 0,1,2,3,4 indicates the level of
                    polarization. (n=0 is unpolarized, n=1 is
                    DZP, n=2 is TZP, etc.). These provide a
                    hierachy of basis sets suitable for DFT and
                    HF calculations.
                    Available for H, C,N,O,F, Si,P,S,Cl
                 = APCn - As PCn, but augmented with a set of diffuse
                    functions.
* * * Effective Core Potential (ECP) bases * * *
         GBASIS = SBKJC- Stevens/Basch/Krauss/Jasien/Cundari
                    valence basis set, for Li-Rn. This choice
                    implies an unscaled -31G basis for H-He.
                = HW - Hay/Wadt valence basis.
                    This is a -21 split, available Na-Xe,
                    except for the transition metals.
                    This implies a 3-21G basis for H-Ne.

* * * Model Core Potential (MCP) bases * * *
         GBASIS = MCP-DZP, MCP-TZP, MCP-QZP -
                    a family of double, triple, and quadruple zeta
                    quality valence basis sets, which are akin to the
                    correlation consistent sets, in that these include
                    increasing levels of polarization (and so do not
                    require "supplements" like NDFUNC or DIFFSP) and
                    must be used as spherical harmonics (see ISPHER).
                    These are available for main group atoms, Li-Rn.
                = IMCP-SR1 and IMCP-SR2 -
                    valence basis sets to be used with the improved
                    MCPs with scalar relativistic effects.
                    These are available for transition metals except
                    La, and the main group elements B-Ne, P-Ar, Ge,
                    Kr, Sb, Xe, Rn.
                    The 1 and 2 refer to addition of first and second
                    polarization shells, so again don't use any of the
                    "supplements" and do use spherical harmonics.
                = IMCP-NR1 and IMCP-NR2 -
                    closely related valence basis sets, but with
                    nonrelativistic model core potentials.
