A novel 1 H imaging method for solids, yielding images reflecting 1 H-13 C dipolar interactions through cross relaxation time T IS , is presented. Phase-alternating multiple-contact cross polarization (PAMC CP) was incorporated into the magic-echo frequencyencoding imaging scheme; the PAMC CP sequen

## Abstract Insect exoskeleton, multiply labeled with ^13^C and ^15^N, was examined by rotational‐echo double‐resonance (REDOR) and double‐cross‐polarization (DCP) magic‐angle spinning ^13^C NMR. Low levels of incorporation of label make the analysis of these samples a practical test of the relativ

The use of indirect detection for signal enhancement in solids is much less common than in liquids, but has attracted renewed interest recently. In this work we describe an indirect detection scheme that offers a large signal enhancement for rare spins in solids. The method uses multiple periods of

It is generally observed that the performance of double-resonance multiple-pulse-based \(J\) cross polarization (DCP) is superior to that of pulsed-free-precession (INEPT)-based sequences for net transfer of coherence between scalar coupled spins. Here, effects of relaxation and radiofrequency field
