MOPAC2007 is free...and
extremely fast. Try PM6 in it. It has a gui that works
with WindowsXP. Google MrMOPAC to locate Jimmy
Stewart.
Cheers!

- I have a mg atom in my molecule that is ligated so I can not use mndo
only... I also have the need to freeze many atoms thus it would be a pain
to use mopac from conseole cause I have to manually change lots of 1's to
0's. Is there any gui you know of that can do that? I tried VEGA but VEGA
does not support PM6. And I have problems running mopac from hyperchem...

- One has to be careful using mndo/d with main group elements.
Where hypervalent elements are not involved it should probably give about
the same results as mndo. How does plain mndo work for you under
these circumstances? I would put my bets on using MOPAC-2007; also
try PM6 therein.

- Hmm for some reasons my questions did not appear... So I will post
them here
- When I do geometry optimization with mndo/d on a biomolecule after
some time some of the atoms bond to each other while doing the same
optimization in spartan with am1 or pm3 does not yield such results. What
may be the cause of this, and how can I prevent that?
- And also when I try to run mopac from hyperchem, it opens the input
file but then it gives a "program teriminated with exit code
0"
- error.. What may be the cause of this?
- Thanks..
