What ab initio programs are availible as freeware? I know of GAMESS, but are there any others. I am specificly looking with programs that may have a more diverse basis set selection for transition metals. I know that ECP parameters can be inputed into GAMESS, but what about additional basis sets, I don't remember reading anything on this topic. Thanks in advance, Steven E. Schafer S.U.N.Y.
