Heteronuclear carbon‐phosphorus chemical shift correlation via heteronuclear multiple quantum coherence is described. Enhanced sensitivity is afforded by inverse detection of 31 P rather than the much less abundant 13 C spin. Correlations via 1 J (CP) and n J (CP), where n = 2, 3, are observable with minor variation in the pulse sequence; a low‐pass J ‐filter was employed in the case of the latter to aid in suppressing responses that would normally arise from 1 J (CP) coupling pathways in the long‐range experiment.
