Abstract

The electronic absorption spectra of ternary complex i.e praseodymium as rare earth metal, amino acid histidine as primary ligand and propane 1,3-diol as secondary ligand in ratio 1:1:2 were recorded in visible region (360-620 nm ) in different solvents i.e water (18.01), methanol(32.04), ethanol(46.07) and acetic acid(60.05). 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.
