Summary A new 2D NMR pulse sequence for E.COSY-type measurement of JHH coupling constants is introduced. It exploits a heteronuclear spin, e.g., 13C, for displacement in the ω1 frequency dimension via a large heteronuclear J coupling. The experiment is demonstrated by application to a heptapeptide at the natural abundance 13C level. It is suitable, for example, for measurement of 3JHH and 4JHH coupling constants in peptides and proteins.
