• The seven coordinate adducts of [Ln(fod)<SUB>3</SUB>]chelates are described. The NMR spectra of diamagnetic and paramagnetic adducts have been discussed. The europium, praseodymium and ytterbium adducts have been scanned as potential shift reagents and these seven coordinate adducts produce large dipolar shifts in the proton magnetic resonances of organic moieties. The dipolar shift produced by [Eu(fod)<SUB>3</SUB>(pz)] in the spectrum of benzyl alcohol is different from that reported. Some interelectronic and spectral parameters (\barβ, <I>b</I><SUP>1⁄2</SUP>, and δ) have been calculated. Ligand field parameter (<I>T</I><SUB>λ</SUB>) and oscillator strengths have been computed and discussed.
