## 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
## Abstract Cross‐polarization (CP) magic angle spinning (MAS) ^6^Li{^1^H} spectra were acquired for three different inorganic lithium compounds. Spectra with a good signal‐to‐noise ratio can be obtained in reasonable times. The poorer signal‐to‐noise ratios shown by spectra acquired in the same e
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
Quantitative measurement of the relative number of rare spins of individual lines in solid state cross polarization NMR has been hampered by the spin-latlice relaxation in the rotating frame and the finite and different cross polarization transfer rates. In this article a simple method which combine
