Calcination of frequencies and forms of normal vibrations of neodymium biglycinate

The results of the X-ray structural, IR and CR spectroscopic studies on the neodymium dimer complex of the (NdCl3·2HGl·3H2O)2 composition, where HGl = N+H3CH2COO-, are presented. The fragmentation calculation of the frequencies and forms of the normal vibrations constituting the complete description of the experimental vibration spectra is accomplished. The set of the force constants of the neodymium dimer complex, which may be applied by the theoretical analysis of the vibration spectra of the rare earth complexes with the α-amino acids is presented
