Hi everyone,
I am currently performing a geometry optimization of an isolated ZnPc (Zinc
Phthalocyanine) molecule in CP2K. My current input uses the
DZVP-MOLOPT-SR-GTH basis set for all atoms.
I would like to improve the accuracy of my calculation by moving to a
TZVP-level basis set. However, I have noticed that TZVP or T2ZVP basis sets
do not seem to be available for the Zinc atom within the standard MOLOPT
library.
Are there recommended, well-tested alternative basis sets for Zinc that are
compatible with the DZVP-MOLOPT-SR-GTH sets used for the C, N, and H atoms
(O as well, since it is needed for the next calculations)?
For reference, I am using the GTH-PBE-q12 pseudopotential.
Best regards,
Samira
