We present the transferred echo double‐resonance multiple‐quantum MAS (TEDOR‐MQMAS) method that allows to analyze under high resolution the through‐bond connectivities between spin‐1/2 and quadrupolar nuclei. This method avoids some of the limitations related to the spin‐lock of half‐integer quadrupolar nuclei under MAS. However, the losses observed during the TEDOR transfer are related to the T ′ 2 constants, and they may thus be more important than those observed during the CP‐MAS transfer, which are related to T 1ρ > T ′ 2 .
