Hi

I can't manage a eht guess for ecp's for ten electrons for Ca, for example the LANL2-DZ-ECP?

What might be the reason??

Hi,

LANL2DZ uses the Hay/Wadt 10 electron ECP. For this you need a EHT defintion prepared for a 10 electron ECP,
which is not (yet) included in TURBOMOLEs basis set library. But you can add this yourself to the file $TURBODIR/basen/ca:

1.) replace in this file the $ehtdef section by:

$ehtdef         definitions=3
1S(DZ)                                    basis=ca DZ
ECP-10               ncore=10  basis=ca LANL2DZ ECP
1S(eht,ecp-18)  ncore=18  basis=ca ecp-18 dz hay & wadt

2.)  add to the $ehtao section the following lines:

ECP-10   ehtdata   (4d20.14)
# SCF energy is      -36.2139710757 a.u.  (virial theorem =  1.361646110)
