## Abstract The problem of bond length alternation in cyclic polyene models as described by the PariserβParrβPople Οβelectron Hamiltonian, together with an empirical quasi harmonic Οβcore potential is investigated using the unrestricted HartreeβFock wave function employing different spatial orbital
