CCL:G: G03:ONIOM /Surface



Thank you all for your suggestions.
I have tried ONIOM with the following line in the route section. However this does not generate any surface (HOMO) in gaussview when opening the checkpoint file. What is wrong ?

*******************************************************************************
#p oniom(uhf/sto-3g*:uhf/sto-3g*)  nosymm  charge

1 2 1 2 1 2  ; two molecules with unity charge on each

                 ; Molecule structure with two layers H & L
point charges
*******************************************************************************

Thanks a lot.

Hi erased,
Try your calculations with ONIOM (QM/QM). It may be helpful in your case.

Dear CCL subscribers,
I have two molecules near each other. How can I assign different amount of charges to each molecule in Gaussian 03?
Thanks in advance.
