✦ Synopsis

Heteronuclear carbon-phosphorus chemical shift correlation via heteronuclear multiple quantum coherence is described. Enhanced sensitivity is afforded by inverse detection of 31P rather than the much less abundant 13C spin. Correlations via 'J(CP) and "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 'J(CP) coupling pathways in the long-range experiment.
