[CP2K:3995] GTH BLYP and B3LYP basis sets and pseudopotentials for Fe

[Lavinia]

Dear Juerg,

 

Thank you so much for your reply. I have one more question. Would you 
recommend using only MOLOPT basis sets for all elements (Fe, H, C, N, O) 
for the heme protein calculations rather than a mix of a MOLOPT basis set 
for Fe and more diffuse GTH basis sets for the other elements? 

 

Best regards,
Lavinia
