Sažetak

The question of the existence of collective modes in molecular systems
is currently attracting much attention both from the theoretical1 and experimental1• 2 point of view. In this study we used Random-Phase-Approximation~ to calculate the transition energies and intensities of three rt-electron systems: benzene, naphthalene and 1,3,5,7,9-decapentaene. Although it is an oversimplification in the framework of RPA the collective modes are defined as the modes the intensities of which are greatly enhanced in comparison with single transitions.
