The absorption spectra of 4f electron transItIons of complexes of ferron (5-sulpho-7-mdoqumohn-8-01) with neodymmm and e&mm m the presence. of dlethylamme were measured Their molar absorptMy at the manmum absorption bands was about 7 5 (at 574 2 nm) times greater for neodymmm and 10 8 (at 519 8 nm)
