Paramagnetic birefringence of heteronuclear erbium(III), thulium(III), and iron(III) d- and dl-tartrates

Abstract

Formation of heteronuclear erbium(III), thulium(III), and iron(III) d- and dl-tartrates was studied by proton magnetic relaxation, pH-metry, and paramagnetic birefringence in combination with mathematical simulation. The paramagnetic birefringence constants mP of the complexes were calculated.
