Hi, folks!

We are using AM1 and PM3 and would like to know if there are any differences
between the two concerning the theoretical basis.
Are the Hamiltonians used different or does the only difference lie in the
parametrisation procedure? We already know that the core-core repulsion terms
vary slightly between the two methods.

Looking forward to get some information!

Bye
