[Ifeffit] Recommendations for DFT/computational chemistry software?

[Eric Breynaert]

Dear Scott,

The answer to this question depends on the compounds you're interested
with and probably also on the software you have access to.  In principle
all computational chemistry software can export a molfile of the
optimised structure. Using xyz coordinates in the molfile you can easily
rig a feff input file.

Best advice is probably to get in touch with a molecular modelling group
and ask them to do the structure optimisations. If that's not an option,
you could try Gaussian. Fairly expensive, but in combination with
Gaussview it's reasonably easy to get the structure optimisation going.
Gamess should do the trick for free. ADF is also an option and VASP can
even handle periodic systems decently.  But as i said initially, the
best advice is to collaborate with a good molecular modelling group.

Regards,

Eric
