Abstract:The molecular orbitals and energy levels ofsgr andpgr electrons in benzene, fulvene and 3,4-dimethylenecyclobutene have been calculated by the LCAO-SCF method, using a basis set of Gaussian orbitals. According to the values of binding energy, the larger stability of benzene is due to a electrons rather than topgr electrons. The main part of dipole moments arises fromsgr electrons.
