The first successful observation of the vicinal 15N,13C spin-coupling constants in a series of amino acids, comprising Val, Ile, Leu and Thr, in which the α-nitrogens are fully replaced with 15N, is described. A Karplus-type dihedral-angle dependence was noted for the coupling constants between the α-nitrogen and γ-carbon nuclei which may, in turn, be applied to the conformational analysis of other amino acids and small peptides. The potential usefulness and limitation of this new parameter in such applications is briefly discussed.
