The molecular orbital interactions in cyclophanes were studied by empolying the model molecules with the assistance of the improved MS-Xa method. The results show that the through-space interactions are exponential flareout with increasing of the distance of two orbitals, and both through-space and through-bond interactions are sizable but these two interactions oppose each other causing the net splltting to be small. Transition-state procedure has been used to calculate ionization potentials, the results are in agreement with the PE-spectra.
