Re^5: How to assign different Basis sets to different atoms?

Dear Sir,
I understood this procedure, except what is meant by the following:

N31 6
D   1
1   0.8 1

In the same example, could you replace the "H" atoms with a Gold atom and send me back the new input file? What inbuilt basis set would be good for adding metals? I donot want to use external basis set. Of course the inbuilt one should provide necessary accuracy. How do I mention 6-31G (d,p) in the same format?

Regards,
