Optical spectral investigations in micellar medium have been carried out for derivative spectra of Pr(III)-quinoline systems. The 4?-4? transition spectra yield sharp bands which were analyzed individually by Gaussian curve analysis. Various energies and intensities of all the transitions were calculated using Judd-Ofelt relation and are perfectly matches with observed value. Low rms deviation confirms the formation of complex. Lande spin orbit coupling (ξ4f), nephelauxetic ratio (β), bonding parameter (b1/2), Percent covalency (δ), have been computed on computer using partial multiple regression analysis. The Judd-Ofelt intensity (T2, T4, T6) parameters also have been evaluated by Using a least-squares fit method. From the magnitude of the bonding parameter (δ).which suggests covalency in complex. By applying the Judd-Ofelt theory a good correlation has been established between the experimental and calculated data. Biological evolutions of these systems on three microorganisms have also been reported first time. A trend for antibacterial studies has been observed.
