Sažetak

The possibility of quantitative predictions of absorption maxima in electronic spectra of unsaturated organic compounds by means of the Pariser-Parr-Pople method with adaptation of parameters is examined. A schematic classification of quantum chemical methods is proposed which is based on the idea of extrapolation from elementary particles (physical constants) to the molecule, from atoms to the molecule and, finally, from fragments to the molecule.
