There is a large amount of literature dealing with the changes produced by various agents in the absorption spectra of the rare-earth metals, amongst the most important contributions being those of de Boisbaudran, Becquerel, Crookes, Muthmann and Stützel, Liveing, and recent papers by H. C. Jones, with various collaborators. Liveing examined the effects of changes of temperature, and of concentration, on the chlorides and nitrates of erbium and “didymium.” He investigated the spectra of solutions in alcohol and in glycerol; of an ammoniacal solution of didymium tartrate (rather similar to that of an alkaline solution of didymium containing sucrose, of which the photograph is given below—photograph 10a), of acidified solutions, and also of borax glass containing didymium. He made an extensive series of photographs of these spectra, and many of the shifts of lines and bands discussed in this paper are to be seen in them, but he states that the plates had to be moved between the exposures “so that no reliance can be placed on the appearance of a shift in such photographs when the amount of such displacement is small.”

Infrared Absorption Spectra

Abstract The infrared absorption spectra of fifteen La3+, Pr3+, Nd3+, and Sm3+ β-diketonates have been studied in the spectral region 750-250 cm-1. The existence of three metal-oxygen vibration modes suggests D3 symmetry for the chelates under study. The stretching force constants, fMO , of the MO bonds have been computed from the observed infrared M-O vibrations using the method of Müller. The value of fMO is nearly constant (~ 2.7x105 dynes/cm) in all the chelates suggesting similar bond strengths.
