# A. Standard Basis Sets

Basis sets and effective core potentials were obtained (1/1/2002) from the Extensible Computational Chemistry Environment (ECCE) Basis Set Database, as developed and distributed by the Molecular Science Computing Facility, Environmental and Molecular Sciences Laboratory which is part of the Pacific Northwest National Laboratory, P.O. Box 999, Richland, Washington 99352, USA, and is funded by the U.S. Department of Energy. The Pacific Northwest National Laboratory is a multi-program laboratory operated by Battelle Memorial Institute for the U.S. Department of Energy under contract DE-AC06-76RLO. Contact David Feller (`df_feller@pnl.gov`) or Deborah Gracio (`gracio@pnl.gov`) for further information.

The names in the NWChem library are consistent with those in the ECCE database and thus may include spaces. The standard NWChem input routines require that strings including spaces are enclosed in quotation marks (`"..."`) or that blanks are escaped with a backslash. As a convenience, basis set names may also have the blanks replaced with underscores. Thus, the following all yield the same basis set for oxygen

      oxygen library "DZP + Diffuse (Dunning)"
      oxygen library DZP\ +\ Diffuse\ (Dunning)
      oxygen library DZP_+_Diffuse_(Dunning)

Case may be ignored when specifying basis set names, but otherwise names should be specified exactly as provided below. A good method is just to cut/paste from the WWW pages since they were generated electronically from the library source.

Errors found in the basis set library of NWChem version 4.4 have been corrected in the current library of NWChem version 4.6. The changes are listed below:

1. Basis Set `"Stuttgart RLC ECP"`
   Element: I
   Effective core potential has been changed and now conforms to the published from by Bergner et al. (Mol. Phys. 1993).

Errors found in the basis set library of NWChem version 4.0 have been corrected in the current library of NWChem version 4.1. The changes are listed below:

1. Basis Set `"aug-cc-pVTZ"`
   Element: Br
   Correction of the diffuse s-exponent from 0.041601 to 0.045593.

2. Basis Set `"cc-pV5Z"`
   Element: Ar
   Questionable contraction coefficients were replaced with HF AO's.

3. Basis Set `"Stuttgart RSC 1997 ECP"`
   Element: Ba
   This basis was called Stuttgart RSC ECP in version 4.0. The 4th s- and p-primitive are now uncontracted.

4. ECP `"LANL2DZ ECP"`
   Element: K and Ca
   The ECP was defined with a core of 18 electrons, inconsistent with the other elements in this series (3d has 10 electron core). The ECP has been replaced with the Hay-Wadt ECP used in Hay-Wadt VDZ.

IMPORTANT NOTE: The Stuttgart basis set and ECP developers have recently developed a new set of Stuttgart RSC ECP's for the Lanthanide series of elements. This new set is now called "Stuttgart RSC ECP", while the previous, and most widely used, set has been renamed to "Stuttgart RSC 1997 ECP" in both the EMSL Basis Set library and in the NWChem basis set library.

Relativistic contractions of standard basis sets for use in the Douglas-Kroll and Dyall-modified-Dirac method have also been included in the library. These are identified by tags following the standard basis set name.

For the Douglas-Kroll method the tag `dk` should be specified:

      oxygen library cc-pVDZ_DK

For the Dyall-modified-Dirac (DMD) method three tags should be specified. The first is a tag for the nuclear model, which can be `pt` or `fi` for a point or a finite Gaussian model (see Section6). The second is a tag for the relativistic Hamiltonian: `sf` is for the spin-free modified Dirac Hamiltonian. The third tags the component type, `fw` for the atomic FW transformed large component, `lc` for the large component and `sc` for the small component:

        oxygen library cc-pvdz_pt_sf_fw
        oxygen library cc-pvdz_pt_sf_lc

Basis sets which are available with either the DmD or DK contractions are indicated in the list below. Additional DmD basis sets are available in the directory `nwchem/contrib/basissets/Dyall_DMD`.

Here is a list of known all-electron non-relativistic, DK and DmD basis sets, effective core potentials with their respective basis sets, fitting basis sets, and Polarization, Diffuse and Core-valence sets of functions, along with the elements included for each. Additional information about each basis set in the NWChem library can be obtained from the online EMSL Gaussian Basis Set library.
