Abstract:

A set of force field parameters for the radical cation of diazabicycle alkane are derived by "substracting" nonbonded molecular mechanics energies (MM2 method) from corresponding molecular orbital energies (MNDO method) using a model compound containing the chemical structure to be parameterized. A general discussion of the N, N’ two-center three electrones bond in radical cations. The results are satisfactory.

Key words: MM2, MNDO, Two-center three electrons bond, Force field parameter
