Abstract : Some plasma effects of the pi-electrons in annulene molecules were studied. The dispersion relation for plasma oscillations, obtained by using Huckel molecular orbitals in the second quantization formalism, was found to describe sound-like waves. The resulting polarization response of the pi-electrons causes a spatial modulation of the interaction potential between two pi-electrons. Correlation is discussed by using the modified interaction potential with a Wannier hamiltonian in pair and quartet equations. The effect of bond alternation is considered in connection with the variation of induced currents in unsaturated annulenes with temperature. (Author)
