POLYCYCLIC AROMATIC COMPOUNDS, cilt.13, sa.1, ss.25-31, 1999 (SCI-Expanded)
Semi-empirical molecular orbital treatment at the level of AM1 type has been performed on the cyclophanes having vinylic bridges. The Hamiltonicity of the cyclophanes is introduced. It has been found that within the isomeric set of these endothermic compounds, the least and the most endothermic ones are Hamiltonian and nonHamiltonian, respectively.
