Description 123-127
Spectroscopic properties of Nd (III)-DOPA in aquated organic solvents are investigated through absorption difference and comparative absorption spectroscopy involving 4f-4f transitions. The change in coordination in different conditions is observed from the absorption intensity analysis when Nd (III) interacts with DOPA. The interaction induced substantial changes in the intensities of 4f-4f bands and their perturbation was reflected through oscillator strength Judd-Ofelt intensity (T) parameters. It is suggested that the changes in the oscillator strengths of different 4f-4f bands and Judd-Ofelt intensity (T) parameters can be used to predict in vivo intracellular complexation of DOPA with Ca(II) through Nd (III)-DOPA absorption spectral studies in-vitro as both Nd (III) and Ca(II) have unique similarity in their coordination behaviour.
