Electronic spectral behavior of poly (Vinylpyrrolodone) in Aqueous Solution i.e. PVP, was determined in aqueous solution including a variety of metalchloride (MgCl2, KCl and BaCl2). The n®p* excitations shifted to longer wavelength depending on the nature and the salt concentration of different cation. The order of effectiveness of cation is K1+ > Ca2+> Mg2+ > Ba2+ for poly (Vinylpyrrolodone) Solution. Change observed in lmax by the salt were correlated with the polymer solvent interactions. These changed were attributed to attraction of PVP molecules with co solute molecules. As the concentration of the co solute increased, a red shift in the peaks was observed indicating an increase in interaction between PVP and co solutes.
