Theoretical simulation of UV absorption spectrum of carbazole and some homocyclic analogues

The UV absorption spectra structures of carbazole, fluorene and dibenzofura ne are studied using the atom monopole-dipole interaction (AMDI) model and atomic dipolar polarisabilities and effective charge given by Fraga. The ab sorption spectra corresponding to these molecules and their self-associatio ns are presented. The original obtained results are discussed and compared to previous works.
