文摘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.
