Abstract
The pi-electronic transitions of 2-aryl- and 2-amino-3-arylazopropenoi c acid esters were interpreted in terms of localisation on molecular f ragments and charge transfer between them. The localisation is charact erised by atomic and the respective fragmental localisation numbers L( A) obtained by a transition density matrix formalism within a standard PPP calculation. A band analysis of the UV spectra based on a normal logarithmic distribution function is presented.
