Dear Raphael,
The ORCA basis set for gold:
{61111111111111111/51111111111/41111111/411/11}
comes from our paper
Pantazis, D.; Chen, X.-Y.; Landis, C.R.; Neese, F. (2008) All Electron
Scalar Relativistic Basis Sets for Third Row Transition Metal Atoms. J.
Chem. Theor. Comp., 4, 908-919
there the entire procedure is described in detail.
see also the geometry benchmarks (ECP versus scalar relativistic all
electron):
Bühl, M.; Reimann, C.; Pantazis, D.A.; Bredow, T.; Neese, F. (2008)
Geometries of Third-row Transition-Metal Complexes from
Density-Functional Theory J. Chem. Theor. Comp., 4, 1449-1459
As we describe in the paper, the connection to the TurboMole library is
the following:
for elements H-Xe we use the primitives from the TurboMole SV, TZV and
QZV basis sets and recontracted in scalar relativistic CASSCF
calculations. For third row transition metals, the primitives have been
generated by us according to simple heuristic rules and contracted as
specified.
The polarization function exponents come from the TurboMole library and
are normally used together with the standard ECP basis sets.
We have done the same for lanthanides and will submit the paper soon. As
far as we can see these basis sets are accurate enough for general use
and denfinitely accurate enough for DFT.
Hope that helps,
best regards,
Frank Neese
