We present novel one-and two-dimensional versions of the 1 -filtered TOCSY experiment. These experiments utilize pulsedfield gradient techniques and INEPT-reverse INEPT magnetization transfer to generate heteronuclear filtering by means of coherence pathway selection. The major advantages of this ap
