摘要：

A simple modification of a refocused INEPT sequence is described that produces single lines from multiplets of the heteronuclear coupled spin systems. Weighted selection of more than one coherence-transfer pathway is accomplished by pulsed field gradients in a single-scan experiment. Applications involve line selections in heteronuclear multiplets and the determination of relaxation times for selected coherences. (C) 1996 Academic Press, Inc.
