• The Eu(fod)<SUB>3</SUB>-induced <SUP>1</SUP>H NMR shifts of <I>n</I>-hexylamine were observed using two kinds of dilution methods. The results are analyzed in terms of the chemical equilibria among the shift reagent (L), substrate (S), 1 : 1 (LS), and 1 : 2 (LS<SUB>2</SUB>) complexes. The association constants and the induced shifts intrinsic to the LS and LS<SUB>2</SUB> complexes are evaluated accurately by fitting the theoretical curves to the observed data. The values obtained are utilized to confirm the validity and usefulness of the extrapolation method proposed previously to determine the shift ratios for the LS complex.
