Applications of Mossbauer spectroscopy to strictly chemical problems of the lanthanides have been few. Nevertheless, some interesting chemical relationships can be derived from physical work—e.g., that of Hiifner on The relative... 

Brix, Hiifner, Kienle, and Quitmann (4) carried out an interesting study on a series of compounds of divalent and trivalent europium using the 21.6-k.e.v., 8.8 nsec, level of europium-151 activated by a SmFs...
