Hi Emilia,
You did not provide information on what the conformational change is
due to, however, since you mention that "it turns over from one side
to the other" it appears that it might be due to dihedral angle(s)
going from one minima to another. You should use look at the example
where charge for molecules with multiple conformations are calculated.
See 0README file in $AMBERHOME/examples/resp_charge_fit and look at
the following example: bis-napthyl One molecule with a two stage
fit on two conformations
