A two‐dimensional heteronuclear multiple‐quantum NMR experiment, based on the DEPT pulse sequence, for the simultaneous determination of the nature of proton‐bearing chemical groups together with the measurement and correlation of carbon and proton chemical shifts is presented. Time and computer memory requirements for the proposed experiment are comparable to the acquisition of a two‐dimensional C,H shift correlation spectrum. The data evaluation of the proposed zero‐quantum carbon‐shift correlated spectrum provides a list of chemical groups corroborated with their carbon and proton chemical shifts.
