[Absorption spectra or hypersensitive transition in the system of neodymium of erbium with amino-acid and 1,10-phenanthroline].
The absorption spectra of f-f hypersensitive transition for the complexes of Nd3+ or Er3+ with some alpha-amino-acids and 1,10-phenanthroline in 95% ethanol solution were studied. The oscillator strength (P) and the spectral parameters (beta, delta, b(1/2)) were calculated. The characteristic of the coordinate bonds of Nd3+ or Er3+ and alpha-amino-acids and the covalent character of the complexes were discussed. The result of the experiment shows that the oscillator strength (P) is related to the numbers of the atoms which form the coordinate bonds.
