[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.
