Suresh Kumar, Mukta Ojha & S.N. Jatolia

Electronic absorption studies of the complexes in solution state with benzothiazole derivative doped in Pr(III)  ion and codoped with Ca+2Mg+2,Sr+2ions  have been calculated in alcoholic (C2H5OH) as well as micellar in medium. In present work, we describes the spectral characterization of the complexes of benzothiazole derivative with Nd(III)  ion and codoped with Ca+2Mg+2,Sr+2  ions in agreement to Green chemistry approach. Various spectroscopic parameters viz- Intensity parameters: Oscillator strength(Pobs×10-6), r.m.s. deviation (σ), Judd-Ofelt Parameter (T2, T4, T6), Bonding parameters : Nephelauxetic ratio (β), Bonding(b1/2), Sinha Covalency (δ %) and Covalency-Angular Overlap (η) Symmetry Parameter (T4 / T2)and Coordination Parameter (T4 / T6)have been computed using partial and multiple regression method. This work describes investigations on Nd(III)  ion and codoped with Ca+2Mg+2,Sr+2 systems with benzothiazole derivatives(2-HBT)in alcoholic as well as micellar in medium.
