Visible and ultra-violet absorption spectra of aqueous solutions of transition metal salts affected by a high-voltage pulse electric discharge

The effect of a high-voltage pulse electric discharge (HVPED) on the electron spectra of CuSO4, Ni(NO3)2, NiCl2, CoSO4, and Co(NO3)2 aqueous solutions is investigated. It is found that the salt system activation by HVPED can change the configurations of electron shells of molecular ions. It is stated that the processes of post-activation structural relaxation of CuSO4/H2O solution are rather long-term. It is shown that the character of the HVPED effect on the electron spectra of solutions significantly depends on the solution composition and the intensity of interparticle interactions therein.
