How accurate do you want to be?
If you have a long number of molecules, then I would suggest that you
use semi-empirical quantum mechanics methods, as those use in MOPAC.
Should you want a more accurate answer (at a bigger cost in computation
times), you can go for other packages like MPQC or GAMESS-US, and use
a good basis set.

GAMESS-US -- http://www.msg.ameslab.gov/GAMESS/
In addition if your structures come in a variety of formats, you will
want to preprocess them with BABEL

Hope this helps.
