ABSTRACT
Electronic polarizability evaluates the deformation caused in the electronic cloud of a species, when ithappens an electronic transition, usually due to the interaction of the radiation electromagnetic with the matter.Due to diversity of applications, experiments have been accomplished by our group, for the obtaining of thevalues of dipole polarizabilities starting from electronic spectra of the coordination compounds. In this work, theywere appraised the electronic polarizabilities of the íons Nd3+ and Er3+ in the compounds Ln(ReO4)3(H2O)9 andLn(ReO4)3(MMNO)6, where Ln = Nd and Er in methanol solutions. The programs SIMP2FOS and POLAZ-Fwere used to evaluate the oscillator strength experimental and for the study of the polarizabilities, respectively.
