Hello,
Despite how wonderful I think Avogadro is for molecular modeling and its
potential for educational purposes, I hesitate to use Avogadro in the
chemistry laboratory when there seems to be such glaring issues as
predicting the dipole moment for simple inorganic molecules such as carbon
dioxide

To be clear, are you asking why MMFF94 is so poor at predicting dipole moments?

Noel - do some of the other Open Babel force fields do a better job at this?

No, he's commenting on a bug. O=C=O clearly should have approximately 0.0D
dipole moment. Regardless of the charges on the individual atoms, the charges
should cancel in a symmetric molecule.
I have no idea the
