## Abstract A coupling constant‐dihedral angle correlation for the HCαCβH system of amino acid residues in peptides has been derived from a set of model compounds covering the full range of dihedral angles. The expression obtained, __J__ = 11.0 cos~2~ θ −1.4 cos θ + 1.6 sin~2~θ, is close to thos
