No, I'm asking about determining those fractional
charges (their actual values) with some theoretical
methods, if they exist (my guess is no).

For example, I'd be much interested in knowing if those
q (in H-F, see above) are, say, + e and - e, or
+ e and - e, where e is the elementary charge.

Dipole moment and a lot of other experimental techniques
I'm aware of, give (each one) different values because
those techniques' outcome depends also on other factors,
besides partial electric charge of the considered atom.
