Electronic polarizabilities were obtained for the salt of nickel trifluorometanesulfonate and for the complex with imidazole, in methanol and acetonitrile solutions. Starting from the electronic spectra, registered in a concentration of 10-3 mol L-1 and using the program SIMP2FOS to calculate the force of the experimental oscillator and POLAZ-F to calculate the electronic polarizabilities, it was possible to notice the different influence of the solvents in the deformation of the electronic cloud of the nickel (II).
