Abstract
The optical absorption spectra of complex of Neodymium and Praseodymium with amino acid Histidine as primary ligand and propane 1,3- diol as secondary ligand have been recorded in visible region (360-900 nm) in ratio (1:2:1) in water. Methanol, Ethanol and Acetic Acid . The energies and intensities of various transitions were calculated using Judd-Ofelt relation and are in good agreement with what we have obtained experimentally.
