The influence of the multiple exchange integrals in the HLSP method for the π-elec-tronic systems has been investigated by means of the illustrations of trans-butadiene and cyclobutadiene molecules. Their importance for the theory, including ionic structures, has been emphasized. For avoiding difficulties in calculations due to the presence of many resonance structures in complex compounds, an approximate method has been proposed. In that method, the degree of energy determinants is diminished.
