[Study of the electronic transitions of azulene and several of it's derivitives and their auto-association by the monopole-dipole atomic interaction (AMDI) model].

The corresponding hydrogen, carbon and nitrogen atomic dipolar polarisabilities and effective charges given by Fraga are used for the determination of theoretical UV absorption spectra of azulene, 1,3-diaza-azulene and 2-phenyl-1,3-diaza-azulene and their self-associations. These spectra are obtained for the first time using the atom monopole dipole interaction model and compared to those given experimentally by other authors.

[UV absorption spectra of 1,1'-binaphtyle and 2,2'-binaphtyle molecules and their self-associations from the atom monopole-dipole interaction (AMDI) model].

The Atom Monopole-Dipole interaction (AMDI) model is used for the first time in calculation of UV absorption spectra of 1,1'-binaphtyl and 2,2'-binaphtyl and their self-associations for the case of frequency-dependant atom polarisability with Lorentzian band shape. UV absorption spectra are obtained from a set of electronic normal modes. The variation of spectra with the conformation of these molecules concord with the results of the medium effect on the corresponding electronic transitions. The calculated auto-association spectra are qualitatively in good agreement with polycyclic aromatic hydrocarbon aggregations behaviour.
