Dear Matt
Could you please let me know if the orbitals projected on the CARTESIAN -
GTOs are normalized?
The basis set (Normalized-Cartesian-GTOs) printed in the MOLDEN formatted
file is consistent with the basis set printed by the NWCHEM code.
When I use the MOLDEN formatted file printed by NWCHEM, my code gives the
right number of electrons.
When I use the orbitals printed by CP2K, I am not able to get the right
number of electrons in the system.
Considering that the basis set is the same, the CP2K orbitals projected on
the Normalized-Cartesian-GTOs could not be normalized.
Best Regards
Luca
