Hi,
If you are using either ADF or Gaussian, you might be interested in trying Xaim
(http://www.quimica.urv.es/XAIM) ... It is an aged-code, only
Linux version, but still working fine.
Hope it helps,
Carles

Dear CCL users;
How I can map electron density difference for AB dimer in order to calculate
charge transfer between A and B fragments. From literature, I know that such an
electron density difference is given by
rho(AB)-rho(A)-rho(B)
where rho is referred to electron density.
What program(s) I can use for such analysis?
Thank you very much for your attention, in advance.
Best regards
Mehdi

Dear Ashley,
Did you try scf=maxcycle=NNN (NNN a number greater than 100).
