Hi Brent,

The JK-fit basis sets are typically those of Weigend - see PCCP 4  
(2002) 4285. CC-type JK-fit basis sets do not yet exist for TMs, you  
could specify some sort of fitting basis for them in the usual way  
within a basis block e.g.


Although the results may need some verification...

Hope this helps,
