CCL:G: electron density difference map



 Sent to CCL by: Carles Bo [cbo*_*ICIQ.ES]
 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).
