Electronic spectra of complexes of neodymium(III) and praseodymium(III) with amino acid

The electronic spectra of complexes of praseodymium(III) and neodymium(III) with amino glycine, alanine and valine have been recorded in the 360-920 nm region in water. The energies and intensities of various transitions calculated using the Judd-Ofelt relation are in good agreement with those obtained experimentally. (author)
