While minimizing Iodophenole I recognized that the atom J had a POSITIVE partial charge of 0,137. Is this correct or could this be due to the fact that the atom J is only incompletely parameterized within AM1? (From the page 3-6 in the MOPAC-manual I concluded that this would not be the case). Could you please help me how to prove the parameterization of J and tell me where to find the file where atoms are parameterized. Many thanks in advance.
