Abstract

1H-n.m.r. spectra ofN,N-dimethylbiuret inDMSO containing LiI, LiCl, NaI, KI, RbI, CsI, MgCl2, CaCl2, SrCl2, BaCl2 and BaI2 have been investigated. The observed shifts of the NH-signal are relatively stronger than the shifts of the NH2-signals. At high salt concentration, coalescence of the NH2-signals and anion effects are observed.

Zusammenfassung

Protonenkernresonanzspektren vonN,N-Dimethylbiuret inDMSO-Lösungen mit LiI, LiCl, NaI, KI, RbI, CsI, MgCl2, CaCl2, SrCl2, BaCl2 und BaI2 wurden aufgenommen. Die beobachteten Verschiebungen des NH-Signals sind stärker als die der NH2-Signale. Bei höheren Salzkonzentrationen wird Koaleszenz der NH2-Signale und das Auftreten von Anioneffekten beobachtet.
