Hai Youyi Peng,
Check if the numbers just after ESP Fit Center and Just before Fit in the
Gaussian Output file. If the numbers are more than 9999 gaussian will print
****. You need to modify it.
Anyway iop(6/33=2) iop(6/41=10) iop(6/42=6) does not give better RESP
fitting. In my calculations I find iop(6/33=2) gives better charge fitting
than using many Iop options. If you are using only iop(6/33=2) , you will
not have this kind of problems becuase it generates less centers.
Hope this will help you.
Best wishes,
Jiten
