A spin–echo sequence is proposed for the suppression of the generally unnecessary strong direct cross‐peaks in two‐dimensional heteronuclear NOE and relayed incoherent transfer spectroscopy. The procedure also increases the intensity of “remote peaks,” thereby enhancing the sensitivity of these techniques.
